A worker is paid Rs 210 for 6 days work. If his total income of the month is Rs 875, for how many days did he work?

Explanation

Let `x` be the number of days for which the worker is paid Rs `875`.
Since, the income of the worker and the number of working days are in direct variation we have:
`⇒210/875=6/x`
`⇒ x= (875×6)/210`
`⇒ x= 5250/210 `
`=>x=25`
∴ The required number of days is `25`.
