Question

A tank filled 4 kl 500 ml of water . 278 L 900 ml was used . How much of water is left?

Answer 1

GiVen:

• Total volume of water in tank = 4 kl 500 ml

• Water used to fill tank = 278 l 900 ml

AnSwer:

Let the capacity of the tank be x.

$: \implies \sf \: \: \: \dfrac{4x}{5} -600= \dfrac{x}{2} \\ \\ : \implies \sf \: \: \: \dfrac{4x - 3000}{5} = \dfrac{x}{2} \\ \\ : \implies \sf \: \: \:2(4x - 3000) = 5x \\ \\ : \implies \sf \: \: \:8x - 6000 = 5x \\ \\ : \implies \sf \: \: \:3x = 6000 \\ \\ : \implies \sf \: \: \:x = \dfrac{6000}{3} \\ \\ : \implies \sf \: \: \:x = 2000$

Therefore, capacity of tank is 2000litres.
