Goa PCS Pre-Screening Mock Test- 7 - Question 26

A Large canister contains 300 liters of Milk. The owner of the canister replaces 30 liters of milk with water. After some time, out of greed, he again replaces 60 liters of milk with water. Meanwhile, a thief came and stole 90 liters of milk and replaced it with water. Find what is the quantity of water in the final mixture.

Detailed Solution for Goa PCS Pre-Screening Mock Test- 7 - Question 26
Some percentage of milk is replaced with water three times

⇒ Remaining milk after replacement of 30 liters of milk with water = 300 × (1−30/300 × 100)

⇒ Remaining milk = 300 × (1−10%)

⇒ Remaining milk = 270 liters

⇒ Remaining milk after replacement of 60 liters of milk with water = 270 × (1−20%)

⇒ Remaining milk = 270 × 80% = 216 liters

⇒ Remaining milk after replacement of 90 liters of milk with water

⇒ Remaining milk = 216 × (1−30%) = 216 × 70% = 151.2 liters

∴ Quantity of water in the final mixture = 300−151.2 = 148.8 liters

Hence, the correct option is (D).

The given bar graph shows the total number of books (fiction and non-fiction) sold in five different book fairs i.e. A, B, C, D and E and also given the number of fiction books sold in these five different book fairs.

Q. If the ratio of the total number of books sold in book fair D to book fair F is 4:7 and the number of fiction books sold in book fair F is 50 more than that of non-fiction books, then find the number of non-fiction books sold in book fair F?

Detailed Solution for Goa PCS Pre-Screening Mock Test- 7 - Question 28

The number of non-fiction books sold in book fair B = 240 – 140 = 100

The number of non-fiction books sold in book fair C = 300 – 120 = 180

The number of non-fiction books sold in book fair D = 200 – 80 = 120

The number of non-fiction books sold in book fair E = 260 - 130 = 130

The total number of books sold in book fair F = 200 * 7/4 = 350

So, the number of non-fiction books sold in book fair F = (350 – 50)/2 = 300/2 = 150
