Question

A tank is 2/5 full. If 16 litres of water is added to the tank, it becomes 6/7 full. The capacity of the tank is:

A) 28 litres B) 32 litres C) 35 litres D) 42 litres

Answer 1

Answer: C) 35 litres.

Explanation:

Let the capacity of the tank be x litres.

 

Then, According to Ques,

(6x/7 - 2x/5) = 16

=> 30x - 14x = 16 × 35

=> 16x = 560

=> x = 560/16

=> x = 35

Thus, the capacity of the tank is 35 litres.
