1. Question
1 pointsCategory: Quantitative AptitudeDirections (15): Study the following information carefully and answer the questions given below.
There is an online company selling shirts which is available in 3 sizes i.e., small, medium, and large. The shirts are sold in threetime slots i.e., 4 am 5 am, 7 am – 8 am and 10 am11 am. The price per shirt for the small, medium and large size is Rs. 400, Rs. 450 and Rs. 500 respectively. The total number of shirts of all three sizes sold in all three slots in a day is 16000.
4 am5 am: 15% of the shirts are sold in this time slot. The ratio of the number of medium size shirt sold to the number of small size shirt sold is 7:2. The number of large size shirts sold is 600 hence the number of small size shirts sold is (A) times the number of large size shirts sold. The total revenue generated by the small size and medium size shirt is Rs. (B) lakh.
7 am – 8 am: The number of shirts sold in this time slot is 225% more than the number of shirts sold from 4 am5 am. The number of large size shirts sold is 25% more than the number of small size shirts sold and the number of medium shirts sold is 11/5^{th} of the number of large shirts sold. The revenue generated by selling small size shirts is (C) % less than the revenue generated by selling large size shirts.
10 am11 am: The remaining shirts are sold in this time slot and the ratio of the number of small, medium and large shirts sold is 8:15:6 respectively. The ratio of revenue generated by selling small size shirts to the revenue generated by selling large size shirts is (D).
What value will come at the place of ‘A’?
Correct
Answer: 1) 2/3
Explanation:
4am5am:
Total number of shirts sold = 16000*(15/100) = 2400
The sum of the number of a small and mediumsize shirt sold = 2400600 = 1800
Number of medium size shirt sold = 1800*(7/9) = 1400
Number of small size shirt sold = 18001400 = 400
Number of small size shirts sold = (2/3)*600 = 400
Hence the number of small size shirts sold is (2/3) (A) times the number of large size shirts sold.Common Explanation:
4am5am:
Total number of shirts sold = 16000*(15/100) = 2400
The sum of the number of small and medium size shirt sold = 2400600 = 1800
Number of medium size shirt sold = 1800*(7/9) = 1400
Number of small size shirt sold = 18001400 = 400
Number of small size shirts sold = (2/3)*600 = 400
Hence the number of small size shirt sold is (2/3) (A) times the number of large size shirt sold.
Revenue generated by selling small size and medium size shirts = 400*400 + 450*1400 = 160000 + 630000 = 790000 = 7.9lakh (B)7am – 8am:
The number of shirts sold = 2400*(100 +225)/100) = 2400*(325/100) = 7800
Let the number of small size shirt sold = 100x and the number of large size shirt sold = 100x*(100+25/100) = 100*(125/100) = 125x
The number of medium size shirt sold = 125x*(11/5) = 275x
100x+125x+275x = 7800
500x = 7800
x = 15.6
Number of small size shirts sold = 100x = 100*15.6 = 1560
Revenue generated by selling small size shirts = 1560*400 = 624000
Number of large size shirts sold = 125x = 125*15.6 = 1950
Revenue generated by selling large size shirts = 1950*500 = 975000
Number of medium size shirts sold = 275x = 275*15.6 = 4290
Required percentage = {(975000624000)/975000}*100 = (351000/975000)*100 = 36% (C)10 am11 am:
The number of shirts sold = 16000(2400+7800) = 1600010200 = 5800
Number of small size shirts sold = 5800*(8/29) = 1600
Revenue generated by selling small size shirt sold = 1600*400 = 640000
Number of medium size shirts sold = 5800*(15/29) = 3000
Revenue generated by selling medium size shirts = 3000*450 = 1350000
Number of large size shirts sold = 5800*(6/29) = 1200
Revenue generated by selling large size shirts = 1200*500 = 600000

Correct
Answer: 4) 36
Explanation:
7am – 8am:
The number of shirts sold = 2400*(100 +225)/100) = 2400*(325/100) = 7800
Let the number of small size shirt sold = 100x and the number of large size shirt sold = 100x*(100+25/100) = 100*(125/100) = 125x
The number of medium size shirt sold = 125x*(11/5) = 275x
100x+125x+275x = 7800
500x = 7800
x = 15.6
Number of small size shirts sold = 100x = 100*15.6 = 1560
Revenue generated by selling small size shirts = 1560*400 = 624000
Number of large size shirts sold = 125x = 125*15.6 = 1950
Revenue generated by selling large size shirts = 1950*500 = 975000
Number of medium size shirts sold = 275x = 275*15.6 = 4290
Required percentage = {(975000624000)/975000}*100 = (351000/975000)*100 = 36% (C)

Question 6 of 10
6. Question
1 pointsCategory: Quantitative AptitudeDirections (6–10): Study the following information carefully and answer the given questions.
A, B, C, and D are four different types of projects. The table below shows the number of days taken by five different persons to complete a project alone.Name Project A Project B Project C Project D Shivani 15 18 16 12 Juhi 12 10 12 16 Garima 16 12 24 15 Dipika 20 8 15 18 Komal 24 15 18 10 Quantity I: Shivani started to work on Project A for a day and left the work, and then Juhi works on the same project for one day and left. In this manner, everyone (In the same order as given in the table) works on the project for one day and leaves. This process continues until work is completed. Then find the time taken to complete project A.
Quantity II: Garima alone completed 5% of project – C and again 15% job was done by Garima and Dipika together. The remaining work was done by Komal alone. Find the number of days Komal did the work.Correct
Answer: 1) Quantity I > Quantity II
Explanation:
Quantity I:
LCM of 15, 12, 16, 20, 24 = 240
Total work = 240 units
Shivani’s per day work = 240/15 = 16units
Juhi’s per day work = 240/12= 20 units
Garima’s per day work = 240/16 = 15
units
Dipika’s per day work = 240/20 = 12 unit
Komal’s per day work = 240/24= 10 unit
Work completed in 5 days work = 16 + 20 + 15 + 12 + 10 = 73
Work completed in 15 days = 73*3 = 216 unit
Work remaining = 240– 216 = 24
Units
Work completed till 16th day = 216+16 = 232
Work left = 240232 = 8
On 17th day Juhi will complete the work in 8/20 = 2/5 day
Therefore, total time taken = 16 (2/5) days
Quantity II:
Shivani has to complete (100% – 15% = 85%) work
Time taken to complete 100% work = 18
Time taken to complete 85% work = (18/100)*85 = 15.3 days
Hence, Quantity I > Quantity IIIncorrect
Answer: 1) Quantity I > Quantity II
Explanation:
Quantity I:
LCM of 15, 12, 16, 20, 24 = 240
Total work = 240 units
Shivani’s per day work = 240/15 = 16units
Juhi’s per day work = 240/12= 20 units
Garima’s per day work = 240/16 = 15
units
Dipika’s per day work = 240/20 = 12 unit
Komal’s per day work = 240/24= 10 unit
Work completed in 5 days work = 16 + 20 + 15 + 12 + 10 = 73
Work completed in 15 days = 73*3 = 216 unit
Work remaining = 240– 216 = 24
Units
Work completed till 16th day = 216+16 = 232
Work left = 240232 = 8
On 17th day Juhi will complete the work in 8/20 = 2/5 day
Therefore, total time taken = 16 (2/5) days
Quantity II:
Shivani has to complete (100% – 15% = 85%) work
Time taken to complete 100% work = 18
Time taken to complete 85% work = (18/100)*85 = 15.3 days
Hence, Quantity I > Quantity II

The table below shows the number of days taken by five different persons to complete a project alone.Name Project A Project B Project C Project D Shivani 15 18 16 12 Juhi 12 10 12 16 Garima 16 12 24 15 Dipika 20 8 15 18 Komal 24 15 18 10 Quantity I: Shivani completed 30% of Project B alone and then the remaining part of the Project B was done by Komal and Juhi together. Find the per day wage of Komal and Juhi together if Shivani got Rs. 4500 as a wage to complete 30% of the project.
Quantity II: Shivani, Juhi, Payal, Komal, and Ruhi together started to complete Project D. Ruhi is 20% less efficient than Shivani who is 50% more efficient than Payal. How much amount did Payal get if the total per day wage given for Project D is Rs 10600?
Correct
Answer: 1) Quantity I > Quantity II
Explanation:
Quantity I:
LCM of 18, 10 and 15= 90
Total work = 90 units
30% of total work = (90/100) * 30 = 27 units
Komal’s per day work = 90/15 = 6 units
Juhi’s per day work = 90/10 = 9 units
Number of days to complete 70% of work by Komal and Juhi together
= 63/15 = 4 (1/5) days = 21/5
Total wage = (4500/30)* 100 = Rs. 15000
70% of total wage = 15000 * (70/100) = 10500
Komal’s and Juhi’s per day wage = 10500/ (21/5) = Rs. 2500
Quantity II:
Total work = LCM of 12, 16, 15, 18, 10 = 720
Per day work done by Shivani = 720/12 = 60 units
Per day work done by Juhi = 720/16 = 45 units
Per day work done by Komal = 720/10 = 72 units
Per day work done by Ruhi will be = 60*{(10020)/100} = 60*(80/100) = 48 units
Per day work done by Payal = 60*{(100/ (100+50)} = 60*(100/150) = 40 units
Work done by Shivani, Juhi, Payal, Komal and Ruhi in one day = 60+45+40+72+48 = 265 units
Per day wage received by Payal = (10600/265)*40 = Rs. 1600
Hence, Quantity I > Quantity IIIncorrect
Answer: 1) Quantity I > Quantity II
Explanation:
Quantity I:
LCM of 18, 10 and 15= 90
Total work = 90 units
30% of total work = (90/100) * 30 = 27 units
Komal’s per day work = 90/15 = 6 units
Juhi’s per day work = 90/10 = 9 units
Number of days to complete 70% of work by Komal and Juhi together
= 63/15 = 4 (1/5) days = 21/5
Total wage = (4500/30)* 100 = Rs. 15000
70% of total wage = 15000 * (70/100) = 10500
Komal’s and Juhi’s per day wage = 10500/ (21/5) = Rs. 2500
Quantity II:
Total work = LCM of 12, 16, 15, 18, 10 = 720
Per day work done by Shivani = 720/12 = 60 units
Per day work done by Juhi = 720/16 = 45 units
Per day work done by Komal = 720/10 = 72 units
Per day work done by Ruhi will be = 60*{(10020)/100} = 60*(80/100) = 48 units
Per day work done by Payal = 60*{(100/ (100+50)} = 60*(100/150) = 40 units
Work done by Shivani, Juhi, Payal, Komal and Ruhi in one day = 60+45+40+72+48 = 265 units
Per day wage received by Payal = (10600/265)*40 = Rs. 1600
Hence, Quantity I > Quantity II

A, B, C, and D are four different types of projects. The table below shows the number of days taken by five different persons to complete a project alone.</tabl
Name Project A Project B Project C Project D Shivani 15 18 16 12 Juhi 12 10 12 16 Garima 16 12 24 15 Dipika 20 8 15 18 Komal 24 15 18 10 Quantity I: Find the time taken by Juhi, Garima, Komal to finish the work D together.
Quantity II: Garim, Dipika and Komal started working together to complete Project C, after 8 days Dipika left the work; Komal left 3 days before the work was completed. In how many days the job was completed?Correct
Answer: 4) Quantity I < Quantity II
Explanation:
Quantity I:
Let the work D is LCM of Total work = LCM of 12, 16, 15, 18, 10 = 720 units
Per day work by Juhi = 720/16 = 45 units
Per day work by Garima = 720/15 = 48 units
Per day work by Komal = 720/10 = 72 units
Per done by Juhi, Garima and Komal together in one day = 45+48+72 = 165 units
Time taken to finish the work = 720/165 = 4 (4/11) days
Quantity II:
Total days to complete work =t
8/15 + (t3)/18 + t/24 = 1
{576 + 60(t – 3) + 45t}/1080 = 1
(576 + 60t – 180 + 45t)/1080 = 1
(396 + 105t)/1080 = 1
396 + 105t= 1080
105t = 684
t = 684/105 = 6 (54/105) = 6 (18/35) days
Hence, Quantity II > Quantity IIncorrect
Answer: 4) Quantity I < Quantity II
Explanation:
Quantity I:
Let the work D is LCM of Total work = LCM of 12, 16, 15, 18, 10 = 720 units
Per day work by Juhi = 720/16 = 45 units
Per day work by Garima = 720/15 = 48 units
Per day work by Komal = 720/10 = 72 units
Per done by Juhi, Garima and Komal together in one day = 45+48+72 = 165 units
Time taken to finish the work = 720/165 = 4 (4/11) days
Quantity II:
Total days to complete work =t
8/15 + (t3)/18 + t/24 = 1
{576 + 60(t – 3) + 45t}/1080 = 1
(576 + 60t – 180 + 45t)/1080 = 1
(396 + 105t)/1080 = 1
396 + 105t= 1080
105t = 684
t = 684/105 = 6 (54/105) = 6 (18/35) days
Hence, Quantity II > Quantity I

Correct
Answer: 2) Project B
Explanation:
Time taken to complete Project – A = A days
1/A = 1/15 + 1/12 + 1/16 + 1/20 + 1/24
1/A = (16+20 + 15 + 12+ 10)/240 = 73/240
A = 240/73 = 3 (21/73) days
Time taken to complete Project – B = B days
1/B = 1/18 + 1/10 + 1/12 + 1/8 + 1/15
1/B = (20 + 36 + 30 + 40+ 24)/360 = 150/360 = 5/12B = 12/5 = 2 (2/5) days
Time taken to complete Project – C = C days
1/C = 1/16 + 1/12 + 1/24 + 1/15 + 1/18
1/C = (45 + 60 + 30 + 48 + 40)/720 = 223/720
C = 720/223 = 3 (51/223)
Time taken to complete Project – D = D days
1/D = 1/12 + 1/16 + 1/15 + 1/18 + 1/10
1/D = (60 + 45 + 48 + 40 + 72)/720 = 265/720 = 53/144
D = 144/53 = 2 (38/53) days
So Project – B will finish first.Incorrect
Answer: 2) Project B
Explanation:
Time taken to complete Project – A = A days
1/A = 1/15 + 1/12 + 1/16 + 1/20 + 1/24
1/A = (16+20 + 15 + 12+ 10)/240 = 73/240
A = 240/73 = 3 (21/73) days
Time taken to complete Project – B = B days
1/B = 1/18 + 1/10 + 1/12 + 1/8 + 1/15
1/B = (20 + 36 + 30 + 40+ 24)/360 = 150/360 = 5/12B = 12/5 = 2 (2/5) days
Time taken to complete Project – C = C days
1/C = 1/16 + 1/12 + 1/24 + 1/15 + 1/18
1/C = (45 + 60 + 30 + 48 + 40)/720 = 223/720
C = 720/223 = 3 (51/223)
Time taken to complete Project – D = D days
1/D = 1/12 + 1/16 + 1/15 + 1/18 + 1/10
1/D = (60 + 45 + 48 + 40 + 72)/720 = 265/720 = 53/144
D = 144/53 = 2 (38/53) days
So Project – B will finish first.
