In time and work the total work is constant the number of men and the number of days or hours are inversely proportional to each other.

Calculations:

1 men complet a toal work in = 15 × 48

⇒ 720 hours

If we have to complete the work in 30 hours = 720 ÷ 30

⇒ 24 men

∴ The number of men required to complete the work in 30 hours is 24.
