Question

I bought wheat worth Rs.$12\frac{1}{2}$, rice worth Rs.$25\frac{3}{4}$ and vegetables worth Rs.$10\frac{1}{4}$.If I gave a hundred-rupee note to the shopkeeper;how much did he return to me.

Answer 1

Money given to shopkeeper$=$Rs.$100$

Total amount of goods bought$=$Rs.$12\frac{1}{2}+25\frac{3}{4}+10\frac{1}{4}$

$=\frac{25}{2}+\frac{103}{4}+\frac{41}{4}$

$=\frac{50+103+41}{4}$

$=$Rs.$\frac{194}{4}$

$\therefore$ Money returned by shopkeeper

$=$Rs.$100-\frac{194}{4}$

$=\frac{400-194}{4}=\frac{206}{4}=\frac{103}{2}=$Rs.$51\frac{1}{2}$
