Question

I purchased 5 litre milk and used 80 percent of it for making sweets. How much milk is left?

Answer 1

Used milk = x litres

80= x/5 x100

x=4 lites

remaining milk = 5-4 = 1 litre

Answer 2

SOLUTION :-

The amount of milk purchased = 5 litres

The percentage of milk used to make sweets = 80% of the 5 litres

So,

80% of 5 litres

= $\frac{80}{100} \times 5$

= 4 litres

$\therefore$ 4 litres of the total 5 litres milk was used to make sweets.

To be found :-

The left milk

= Total litres of purchased milk - litres of milk used for making sweets

= 5 litres - 4 litres

= 1 litre

Hence,

1 litre of milk is left
