Question

The monthly consumption of milk in a family was 110 litres. If due to some reasons it decreased by 20%, find the present consumption of milk. *

Answer 1

Decrease consumption of milk = 20%
= 20% of 100
= 20/100*100
= 20 liters
Now,
The present consumption of milk = 110 liters - 20 liters
= 90 liters

Answer 2

Decrease consumption of milk = 20%

= 20% of 100

= 20/100*100

= 20 liters

Now,

The present consumption of milk = 110 liters - 20 liters

= 90 liters
