Question 1 of 10
1. Question
1 pointsCategory: Quantitative AptitudeThe selling price of a book is Rs. 250 when it is sold at a profit of 25%. At least how many books one must sell to purchase a bag costing Rs. 1000 if only profit money obtain by selling books is used to buy the bag?
Correct
Answer: 2) 20
Explanation:
Given, the selling price of the book = Rs. 250
Cost price of the book
= 250*(100/125)
= 200
Profit
= 250200
= Rs.50/per book
Therefore, number of books one must sell to purchase a bag costing Rs. 1000
= (1000/50)
= 20Incorrect
Answer: 2) 20
Explanation:
Given, the selling price of the book = Rs. 250
Cost price of the book
= 250*(100/125)
= 200
Profit
= 250200
= Rs.50/per book
Therefore, number of books one must sell to purchase a bag costing Rs. 1000
= (1000/50)
= 20 
Question 2 of 10
2. Question
1 pointsCategory: Quantitative AptitudeA glass contains 350 ml of wine. Some quantity of wine is taken out and 2/3rd of that quantity of wine, water is added in the glass. Now the ratio of wine to water in the glass becomes 2:1. What is the quantity of wine which is taken out?
Correct
Answer: 3) 150ml
Explanation:
Let the quantity of wine removed
= 3x ml
Quantity of water added
= (2/3)*(3x)
= 2x ml
ATQ,
(3503x)/2x = 2/1
3503x = 4x
350 = 4x+3x
350 = 7x
x = 50 ml
The quantity of wine which is taken out = 3x =3*50 = 150 mlIncorrect
Answer: 3) 150ml
Explanation:
Let the quantity of wine removed
= 3x ml
Quantity of water added
= (2/3)*(3x)
= 2x ml
ATQ,
(3503x)/2x = 2/1
3503x = 4x
350 = 4x+3x
350 = 7x
x = 50 ml
The quantity of wine which is taken out = 3x =3*50 = 150 ml 
Question 3 of 10
3. Question
1 pointsCategory: Quantitative AptitudeA, B and C started a business with an initial investment of Rs. 1200, Rs. 1500 and Rs. 1800 respectively. From 10th month onwards they each decided to invest Rs. 150 more on the starting of each month. If the total annual profit is Rs.1260 then find the difference between the profit of B and C.
Correct
Answer: 5) Rs. 80
Explanation:
Ratio of profit (A: B: C)
= (1200*9 + 1350 + 1500 + 1650): (1500*9 + 1650 + 1800 + 1950): (1800*9 + 1950 + 2100 + 2250)
= 15300: 18900: 22500
= 153: 189: 225
= 51:63: 75
=17:21:25
Difference in profit of B and C = (1260)*{(2521)/ (17+21+25)} = (1260)*(4/63) = 20*4 = Rs. 80Incorrect
Answer: 5) Rs. 80
Explanation:
Ratio of profit (A: B: C)
= (1200*9 + 1350 + 1500 + 1650): (1500*9 + 1650 + 1800 + 1950): (1800*9 + 1950 + 2100 + 2250)
= 15300: 18900: 22500
= 153: 189: 225
= 51:63: 75
=17:21:25
Difference in profit of B and C = (1260)*{(2521)/ (17+21+25)} = (1260)*(4/63) = 20*4 = Rs. 80 
Question 4 of 10
4. Question
1 pointsCategory: Quantitative AptitudeFind the total distance covered when the boat travels upstream for 4 hours and downstream for 8 hours. Sum of the speed of a boat in upstream and downstream is 60 km/hr. Speed of the boat in still water is 700% more than the speed of the stream.
Correct
Answer: 5) 375km
Explanation:
Speed of boat in still water
= (Sum of speed of a boat in upstream and downstream)/2
= 60/2
= 30km/h
Let the Speed of stream = x km/h
ATQ,
Speed of boat = x + 700% of x
30 = x + 7x
30 = 8x
x = 30/8 = 3.75 km/h
Upstream speed
= (303.75)
= 26.25km/h
Distance covered in upstream in 4 hours
= 26.25*4
= 105km
Downstream speed
= (30+3.75)
= 33.75km/h
Distance covered in downstream in 8 hours
= 33.75*8
= 270
Total distance covered
= 105+270
= 375kmIncorrect
Answer: 5) 375km
Explanation:
Speed of boat in still water
= (Sum of speed of a boat in upstream and downstream)/2
= 60/2
= 30km/h
Let the Speed of stream = x km/h
ATQ,
Speed of boat = x + 700% of x
30 = x + 7x
30 = 8x
x = 30/8 = 3.75 km/h
Upstream speed
= (303.75)
= 26.25km/h
Distance covered in upstream in 4 hours
= 26.25*4
= 105km
Downstream speed
= (30+3.75)
= 33.75km/h
Distance covered in downstream in 8 hours
= 33.75*8
= 270
Total distance covered
= 105+270
= 375km 
Question 5 of 10
5. Question
1 pointsCategory: Quantitative AptitudeThere are 6 balls in bag A and 10 balls in bag B. The number of white balls in bag A and bag B is 3 and 4 respectively. If a bag is chosen randomly and two balls are drawn at random from it, what is the probability that at least one ball is white if the ball is not replaced?
Correct
Answer: 5) 11/15
Explanation:
At least one white ball can be chose in three ways:
1. Both the balls are white
2. First ball is white and second is not white
3. First ball is not white and second ball is white.
Probability of selecting a bag = ½
Probability of choosing at least one white ball from first bag
= ½ *(3/6*2/5 + 3/6*3/5 + 3/6*3/5)
= ½*(6/30 + 9/30 + 9/30)
= ½*(24/30)
= 12/30
= 2/5
Probability of choosing at least one white ball from second bag
= ½*(4/10*3/9 + 4/10*6/9 + 6/10*4/9)
= ½*(12/90 + 24/90 + 24/90)
= ½*(60/90)
= 30/90
=1/3
Final probability
= (2/5) + (1/3)
= (11/15)Incorrect
Answer: 5) 11/15
Explanation:
At least one white ball can be chose in three ways:
1. Both the balls are white
2. First ball is white and second is not white
3. First ball is not white and second ball is white.
Probability of selecting a bag = ½
Probability of choosing at least one white ball from first bag
= ½ *(3/6*2/5 + 3/6*3/5 + 3/6*3/5)
= ½*(6/30 + 9/30 + 9/30)
= ½*(24/30)
= 12/30
= 2/5
Probability of choosing at least one white ball from second bag
= ½*(4/10*3/9 + 4/10*6/9 + 6/10*4/9)
= ½*(12/90 + 24/90 + 24/90)
= ½*(60/90)
= 30/90
=1/3
Final probability
= (2/5) + (1/3)
= (11/15)
