Question 8.

Vidya and Pratap went for a picnic. Their mother gave them a water bottle that contained 5 litres of water. Vidya consumed \(\frac{2}{5}\) of the water. Pratap consumed the remaining water,

i) How much water did Vidya drink?

Solution:

Total water = 5 liters

Given that,

Vidya drank \(\frac{2}{5}\) of the water.

∴ Water Vidya drank = \(\frac{2}{5}\) × Total water

Vidya drank 2 litres of water.

(ii) Fraction of water Pratap drank

Hence Pratap consumed \(\frac{3}{5}\)of the total quantity of water.
