Question

A tank consists of 1/3" part of water, if
200 litres of water is added in the tank,
the tank will contain half litre of water.

Then how many litres of water is in the
tank?
A) 600 litres
B) 1200 litres
C) 1000 litres
D) 300 litres
​

Answer 1

Step-by-step explanation:

let part of water be y.

As per question,

1/3 (y) + 200 = 1/2 (y)

1/2(y) - 1/3(y) = 200

1/6(y) = 200

therefore, y = 1200 ltr.

option (B) is the correct answer.
