Question

if 1/3 of a tank holds 80 litres of
water, then the quantity of water
that 1/2
tank holds is :
(1) 240 litres (2) 120 litres
(3)
litres (4) 100 litres
non​

Answer 1

SOLUTION :

Given that,

Amount of water 1/3 part of tank holds = 80 L

Let us solve this word problem by unitary method.

So,

Amount of water 1 tank will hold =

$80 \div \frac{1}{3}$

$80 \times 3$

$240 \: litres$

So,

Amount of water 1/2 part of tank will hold =

$\frac{1}{2} \times 240$

$120 \: litres$

Hence,

The quantity of water that 1/2 water tank holds is 120 Litres.

The correct option is (2)
