Question

The capacities of three water tanks are in the ratio 2 :3:5.The smallest of them can hold 2500 litres. How many litres can the other two hold?

Answer 1

2=2500
so1=1250
3=1250*3=3750
5=1250*5=6250
total=2500+3750+6250
=12500litres

Answer 2

The other two tanks can hold 10000 litres.

• The capacities of three water tanks are in the ratio 2:3:5.

• Let the common multiple be x.

• Now the capacities of tanks are

Capacity of Tank 1 = 2x

Capacity of Tank 2 = 3x

Capacity of Tank 3 = 5x

• The smallest tank capacity is 2500 litres .

Therefore, 2x = 2500

x = 1250.

• Capacity of Tank 2 is 3x = 3×1250 = 3750 litres

• Capacity of Tank 3 is 5x = 5×1250 = 6250 litres

• Capacity of Tank 2 and Tank 3  = 3750 + 6250 = 10000 litres
