Question

A water tank is 2-5 full. when 700 litres of watwer is added the tank is 3-4 full. what is capacity of the tank?

Answer 1

The volume of the container is 2000L

Explanation step by step:

Statement data:

Container 2/5 full

700L of water are added.

Container 3/4 full

What is the total volume?

Initially we have a volume of 2/5 of the total volume ie;

2 / 5Vt

In addition to the 700 liters of water, the container will have 3/4 of the total volume, so we propose the following:

3 / 4Vt = initial volume + quantity added

3/4 Vt = 2/5 Vt + 700L

We cleared Vt:

Vt = 700L * (20/7)

Vt = 2000L
