CSAT Questions and Solutions
Q11. In a class, 60% of the students are male and 32% of students fail the quarterly exam. If one third of the males failed, what fraction of females passed the quarterly exam?
(a) 2/7
(b) 6/16
(c) 7/10
(d) 4/7
Correct option:(c)
Explanation:
In a class, 60% are Males. So, females = 40%
Now, one-third of male students fail.
Failed male students = 1/3 * 60% = 20%
Total failed students = 32%
Failed female students = Total failed students - failed male students = 32% - 20% = 12%
Total female students = 40%
Fraction of females passed = (40-12)/40 = 28/40 = 7/10
Q12. How many zeros are at the end of the product 1*2*3*4………*19*20 ?
(a) 10
(b) 8
(c) 6
(d) 4
Correct option: (d)
Explanation:
Zero is there when we have 2 x 5. This creates 10 and as many pairs of 2 x 5 are there we will have same number of zeros at the end. Now, there are 10 twos in the series as there are 10 even numbers from 1 to 20. So, we need to check the number of fives. We have fives at 5, 10 (5 x 2), 15 (5 x 3) and 20 (5 x 2 x 2).
So, the number of zeros at the end will be 4.

Q14. An 8-digit number 3452456B leaves remainder 0 when divided by 3. How many values of B are possible?
(a) 2
(b) 3
(c) 4
(d) 6
Correct option: (b)
Explanation:
This is a question based on rules of divisibility. The rule of divisibility of 3 is that the sum of all the digits of the number should be divisible by 3. We have 3 + 4 + 5 + 2 + 4 + 5 + 6 + B = 29 + B, which is completely divisible by three. So, B can take value as 1, 4, or 7. Hence 3 values are possible for B.
Q15. A milkman adds 500 ml of water to each litre of milk he has in a container. He sells 30 litres of mixture from the container and adds 10 litres of milk in the remaining. The ratio of milk and water in the final mixture is 11:5. Find the initial quantity of milk in the container.
(a) 100 litres
(b) 120 litres
(c) 150 litres
(d) 180 litres
Correct option: (b)
Explanation:
Let initial quantity of milk be 10x
After adding water, total quantity =15x
quantity of milk =10x
After selling 30 litre of mixture and adding 10 litre milk, total quantity =(15x – 30 + 10) = (15x−20)
quantity of milk =10x − (30 ×10x/15x)+10 = 10x-10
(10x−10)/(15x−20) = 11/11+5
⇒ x = 12
Initial quantity of milk in the container = 10x = 120 litres.
Statement 1 is incorrect: The act provides for the maintenance of the religious character of any place of worship as it existed on the 15th day of August 1947.
