Question

Bachhu Manjhi earns $₹24000$ in $8$ months. At this rate, in how many months does he earn $₹42000$?

Answer 1

We have,

Money earned within $8\mathrm{month}=₹24000$

Money earned within $1\mathrm{month}=\frac{24000}{8}=₹3000$

$\begin{array}{rcl}\therefore \mathrm{Number}\mathrm{of}\mathrm{months}\mathrm{he}\mathrm{earned}₹42000& =& \frac{\mathrm{Total}\mathrm{Amount}}{\mathrm{Money}\mathrm{earned}\mathrm{in}1\mathrm{month}}\\ & =& \frac{42000}{3000}\\ & =& 14\mathrm{months}\end{array}$
∴Bachhu Manjhi earned $₹42000$ in $14\mathrm{months}$.
