Question

If Manoj earns $Rs1200$ in $10$ days, then:

Manoj's income for $32$ days is $Rs$______

Answer 1

Given that,

Manoj earns $Rs1200$ in $10$ days

By unitary method,

Manoj earning in $1$ day $=\frac{Rs1200}{10}=Rs120$

Multiply both side by $32$

Therefore, Manoj earning in $32$ days $=Rs120\times 32=Rs3840$

Hence, Manoj's income for $32$ days is $Rs3840$
