Question

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

1. How much water did Vidya drink?
2. What fraction of the total quantity of water did Pratap drink?

Answer 1

i. Part of the water drink by Vidya = ${\displaystyle \frac{2}{5}}$

= ${\displaystyle \frac{2}{5}\times 5 \text{litres}}$

= 2 liters

Hence, the quantity of water drink by Vidya = 2 litres

ii. Fraction of amount of water drink by Pratap = Total water – Part of water drink by Vidya

= ${\displaystyle 1-\frac{2}{5}}$

[Here the total portion of water is 1.]

= ${\displaystyle \frac{5-2}{5}}$

= ${\displaystyle \frac{3}{5}}$

Hence, the portion of water drink by Pratap = ${\displaystyle \frac{2}{5}}$

Hence, quantity of water drink by Vidya = 2 and litres and share of water drink by Pratap = ${\displaystyle \frac{3}{5}}$
