Question

the volume of water in a tank is twice of that in the other if we draw out of 25 litres from the first and added to the other the volumes of the water in which tank will be the same find the volume of the water in its tank

Answer 1

let the volume of water in the second tank be x

and the volume of water in the first tank = 2x

ATQ

2x - 25 = x + 25

2x - x = 50

x = 50

now ,

volume of water in ist tank = 2x = 2(50) = 100 litres

Answer 2

let the volume of one tank be x L
let the volume of the other tank = 2xL
the volume of the water in the first tank +25=2x-25
x=50 so volume of water in one tank=50L and volume of the water in the other tank=2X50=100L
