Question

A workman is paid Rs.$150$ for each day he works and is fined Rs.$50$ for each day he is absent. In the month of $30$ days he earned Rs.$2100$. For how many days did he remain absent?

Answer 1

Let the workman was absent for $n$ days.

Hence, he was worked for $(30-n)$ days.

His total wage$2100=150\times (30-n)-50n$

$⟹2100=4500-200n$

$⟹n=12$

Hence, he was absent for $12$ days.
