Question 1 of 10
1. Question
1 pointsCategory: Quantitative AptitudeQ. (15) Study the following table carefully to answer the given questions
V, Q and Z worked on File E. X and Y alone can complete whole File E in 20 and 30 days respectively. Q who is 3/2 times efficient than X and Ytogether replaces both of them and worked for same number of days for which X and Yhad to work. V completed 1/12th of the work. Find in how many days all V, X, Y, and Z can complete the Files E together.
Correct
Answer : 2. 6
Explanation
X and Y together can complete work in 12 days [1/20 + 1/30 = 5/60 =12 days]
Efficiency Q: (X+Y) = 3/2: 1 = 3: 2
So, ratio of number days = 2: 3
So Q can complete whole work in 2/3 * 12= 8 days
Now Q worked for (2+3) = 5 days â€“ total days for which X and Y worked.
So Q completed 5/8 of work, V completed 1/12 of work. 1/12 is uncompleted work. Let x is no. of days in
Which Z can complete whole work. So
Vâ€™s work + Qâ€™s work + Zâ€™s work = 1 â€“ uncompleted work
1/12 + 5/8 + 5/x = 1 â€“ 1/12
Solve, x = 24 = no. of days in which Z can alone complete File E.
V completed 1/12th work in 2 days, so he can complete whole Files in 2*12 = 24 days
V = 24, X = 20, Y = 30, Z = 24
So, together they can complete in = 1/24 + 1/20 + 1/30 + 1/24 = 1/6 = 6 daysIncorrect
Answer : 2. 6
Explanation
X and Y together can complete work in 12 days [1/20 + 1/30 = 5/60 =12 days]
Efficiency Q: (X+Y) = 3/2: 1 = 3: 2
So, ratio of number days = 2: 3
So Q can complete whole work in 2/3 * 12= 8 days
Now Q worked for (2+3) = 5 days â€“ total days for which X and Y worked.
So Q completed 5/8 of work, V completed 1/12 of work. 1/12 is uncompleted work. Let x is no. of days in
Which Z can complete whole work. So
Vâ€™s work + Qâ€™s work + Zâ€™s work = 1 â€“ uncompleted work
1/12 + 5/8 + 5/x = 1 â€“ 1/12
Solve, x = 24 = no. of days in which Z can alone complete File E.
V completed 1/12th work in 2 days, so he can complete whole Files in 2*12 = 24 days
V = 24, X = 20, Y = 30, Z = 24
So, together they can complete in = 1/24 + 1/20 + 1/30 + 1/24 = 1/6 = 6 days 
Question 2 of 10
2. Question
1 pointsCategory: Quantitative AptitudeQ. (15) Study the following table carefully to answer the given questions
X and Y can complete the whole File D in 6 days working together. V is 20% more efficient than Y and 40% less efficient that X. How many days did Z work on File D if Z can complete whole File D in 18 days?
Correct
Answer : 1. 1
Explanation
Efficiency â€” V: Y = 120: 100 = 6: 5
So days ratio = 5: 6
Similarly, V: X = 60: 100 = 3: 5, so days 5: 3
X/V = 3/5, V/Y = 5/6
So ratio of days for X: V: Y is 3: 5: 6 â€¦â€¦â€¦â€¦ (1)
Now â€” X and Y can complete the whole File D in 6 days working together, and ratio of no. of days in which
They can complete work alone is X and Y from (1) is 3: 6 = 1: 2
So
(1/x) + (1/2x) = 1/6
x = 9
So X can complete work in 9 days, Y in 18 days and then V in 15 days
Now, let Z worked for â€˜yâ€™ days on File D. So
(1/15) *5 + (1/9) * 3 + (1/18)* 2 + (1/18)* y = 1 â€“ 1/6
y = 1 dayIncorrect
Answer : 1. 1
Explanation
Efficiency â€” V: Y = 120: 100 = 6: 5
So days ratio = 5: 6
Similarly, V: X = 60: 100 = 3: 5, so days 5: 3
X/V = 3/5, V/Y = 5/6
So ratio of days for X: V: Y is 3: 5: 6 â€¦â€¦â€¦â€¦ (1)
Now â€” X and Y can complete the whole File D in 6 days working together, and ratio of no. of days in which
They can complete work alone is X and Y from (1) is 3: 6 = 1: 2
So
(1/x) + (1/2x) = 1/6
x = 9
So X can complete work in 9 days, Y in 18 days and then V in 15 days
Now, let Z worked for â€˜yâ€™ days on File D. So
(1/15) *5 + (1/9) * 3 + (1/18)* 2 + (1/18)* y = 1 â€“ 1/6
y = 1 day 
Question 3 of 10
3. Question
1 pointsCategory: Quantitative AptitudeQ. (15) Study the following table carefully to answer the given questions
file C was to be completed in 6 days. To complete Files in time, all V, X, Y and Z decided to work in pairs in alternate days. V and Y on 1st day, X and Z on 2nd day, V and Y on 3rd, and so on. But they could not complete Files in time. What percent of File C remain uncompleted if V, X, Y and Z can complete whole File C in 12, 18, 20 and 15 days respectively?
Correct
Answer : 3. 70/3%
Example
File is to be completed in 6 days. They all worked in pairs on alternate means all worked for 3 days each.
On 1st day, work completed by V and Y = 1/12 + 1/20 = 2/15
On 2nd day, work completed by X and Z = 1/18 + 1/15 = 11/90
1st pair worked for 3 days, so work completed by them = 2/15 * 3 = 2/5
Similarly, by X and Z = 11/90 * 3 = 11/30
So part of Files uncompleted= 1 â€“ (2/5 + 11/30) = 7/30
So % = 7/30 * 100 = 70/3%Incorrect
Answer : 3. 70/3%
Example
File is to be completed in 6 days. They all worked in pairs on alternate means all worked for 3 days each.
On 1st day, work completed by V and Y = 1/12 + 1/20 = 2/15
On 2nd day, work completed by X and Z = 1/18 + 1/15 = 11/90
1st pair worked for 3 days, so work completed by them = 2/15 * 3 = 2/5
Similarly, by X and Z = 11/90 * 3 = 11/30
So part of Files uncompleted= 1 â€“ (2/5 + 11/30) = 7/30
So % = 7/30 * 100 = 70/3% 
Question 4 of 10
4. Question
1 pointsCategory: Quantitative AptitudeQ. (15) Study the following table carefully to answer the given questions
V who can complete File B in 20 days, worked for 6 days. The ratio of number of days in which X and Ycan complete Files 2 alone is 5: 8. Z could not come to work for Files 2. Find the number of days in which Xand Y can complete 13/30 of File B together, given that if Z who can complete work in 12 days had also joined the File for 4 days, the Files would have been completed.
Correct
Answer : 1.4
Example
Number of days in which X and Y can complete File B alone is 5x and 8x respectively.
Now if Z also joined for 4 days, Files would have been completed, means
6/20 + 3/5x + 4/8x + 4/12 = 1
11/10x = 11/30
x = 3
So X can complete Files in 5x = 15 days, and Y in 8x = 24 days.
So 13/30 work, X and Y together â€“ (1/15 + 1/24)*y = 13/30
y = 4 daysIncorrect
Answer : 1.4
Example
Number of days in which X and Y can complete File B alone is 5x and 8x respectively.
Now if Z also joined for 4 days, Files would have been completed, means
6/20 + 3/5x + 4/8x + 4/12 = 1
11/10x = 11/30
x = 3
So X can complete Files in 5x = 15 days, and Y in 8x = 24 days.
So 13/30 work, X and Y together â€“ (1/15 + 1/24)*y = 13/30
y = 4 days 
Question 5 of 10
5. Question
1 pointsCategory: Quantitative AptitudeQ. (15) Study the following table carefully to answer the given questions
V and X started working on File A. They completed 1/3rd of work after which they left and Y joined the File. Y can complete the whole File in 12 days. After Y worked for his assigned number of days, Z joined the files and worked for his assigned number of days. Find the number of days in which z can complete the whole File A?
Correct
Answer : 3. 18
Explanation
V and X complete 1/3rd, Y completed 1/12 * 2 = 1/6
Completed work before Z joined is 1/3 + 1/6 = 1/2
Z = 1 â€“ 1/2 = 1/2 of work
Now File uncompleted after Z left = 1/3
So Z did = 1/2 â€“ 1/3 = 1/6 of work
He worked for 3 days, means he complete 1/6th of work in 3 days.
He can do complete File A in 6/1 * 3 = 18 daysIncorrect
Answer : 3. 18
Explanation
V and X complete 1/3rd, Y completed 1/12 * 2 = 1/6
Completed work before Z joined is 1/3 + 1/6 = 1/2
Z = 1 â€“ 1/2 = 1/2 of work
Now File uncompleted after Z left = 1/3
So Z did = 1/2 â€“ 1/3 = 1/6 of work
He worked for 3 days, means he complete 1/6th of work in 3 days.
He can do complete File A in 6/1 * 3 = 18 days
