Question

Rekha had $₹25\frac{1}{2}$ in her purse. She spent money $₹17\frac{3}{4}$ on lunch. What does she have now in her purse?

Answer 1

Total money Rekha had in the purse = $₹25\frac{1}{2}$= $₹\frac{25\times 2+1}{2}=₹\frac{51}{2}$
Amount of money spent on lunch = $₹17\frac{3}{4}$ = $₹\frac{17\times 4+3}{4}=₹\frac{71}{4}$
The remaining amount in the purse = $₹\frac{51}{2}-₹\frac{71}{4}$
= $\frac{51\times 2-71}{4}=\frac{102-71}{4}$ = $\frac{31}{4}$
So, the remaining amount in the purse is $₹\frac{31}{4}or₹7\frac{3}{4}$.
