Question 8.
Vidya and Pratap went for a picnic. Their mother gave them a water bag that contained 5 litres of water. Vidya consumed \(\frac{2}{5}\) the remaining water. Pratap consumed the remaining water.
(i) How much water did Vidya drink ?
(ii) What fraction of the total quantity of water did Pratap drink ?
Solution:
(i) Vidya consumed \(\frac{2}{5}\) of the water
∴ 5 litres of \(\frac{2}{5}\) = 5 x \(\frac{2}{5}\) = 2 litres
∴ Vidya drink = 2 litres.
(ii) Now 5 litres – 2 litres = 3 litres 3
∴ Pratap drink = \(\frac{3}{1}\) litres = 3 litres.
