Question

The volume of water in a tank Aand B is in the ratio 4:5 if the volume of water in the tank A increased by 30 percentage the volume in tank B must be increased so that the both tanks have the same volume of water

Answer 1

The increased volume of tank B is 4% .

Given data :

Ratio of volume of tank A and B = 4:5

Water increase in tank A = 30%

Let,the volume of tank A and B = 4x and 5x (assume x = variable to calculate the volume of A and B)

Increased volume of tank A

= Initial volume + Increase

= {4x+(4x×30/100)}

= (4x + 6x/5)

= 26x/5

So,the increased volume of tank B to become same as tank A = 26x/5 - 5x = 26x-25x/5 = x/5

So,the percentage of increased volume = 100 × x/5/5x = 100× x/5 × 1/5x = 4%

The increased volume of tank B is 4% to be equal with tank A.
