Question

An employee earns $Rs.72,000$ in $3$ months.
a) How much does he earn in $7$ months?
b) In how many months will he earns $Rs.3,60,000$?

Answer 1

Amount earned in $3$ months= $Rs.72,000$
Amount earned in $1$ month= $\frac{Rs.72,000}{3}=Rs.24,000$
a) amount earned in $7$ months=$Rs.24,000\times 7=Rs.1,68,000$
b) Months in which $Rs.3,60,000$ will be earned = $\frac{Rs.3,60,000}{Rs.24,000}=15\text{months}$
