Question

There was 3 times as much water in Tank A than in Tank B. After 50 litres of water was added to each tank, the ratio of the amount of water in Tank A to the amount of water in Tank B is 5 : 2. How much more water(in litres) was there in Tank A thank in Tank B?

Answer 1

Let water in tank B be x
So, water in tank A = 3x
Now,
As per question

$\frac{3x + 50}{x + 50} = \frac{5}{2}$
Or,
2(3x + 50) = 5 ( x+50)
Or,
6x + 100 = 5x + 250
Or, x = 150

Therefore,
Water in tank B was 150 litres
And in tank A was = 3* 150 = 450 litres

So, difference of water =450-150 = 300

Therefore, tank A had 300 litres water more than tank B.

Hope this will be helping you
