Question

The cost of $15$envelops is $Rs60$.How many envelops can be bought for $Rs32?$

Answer 1

Cost of $15$ envelops = $Rs60$

Cost of $1$ envelop = $\frac{60}{15}=Rs4$

Total number of envelop in $Rs32$ $=\frac{Total\cos t}{\cos tof1envelop}=\frac{32}{4}=8$

Hence, total number of envelop can be bought in $Rs32$ is $8$.
