Question

Aishah poured 17 litres of water into 3 containers. Container A had 3 times as much water as Container B. Container C had 2.5 litres of water fewer than Container B. Find the amount of water in Container B in litres.

Answer 1

Let the amount of water in Container B be x litres.

Then, the amount of water in Container A is 3x litres.

And the amount of water in Container C is (x - 2.5) litres.

The total amount of water in the three containers is 17 litres, so we have:

x + 3x + (x - 2.5) = 17

5x - 2.5 = 17

5x = 19.5

x = 3.9

Therefore, the amount of water in Container B is 3.9 litres.
