If 36 persons can finish 50% of work in 12 days In how many days 72 person can finish the complete work?

12

36 Person can finish 50% of the work in ⇒ 12 days

36 Person can finish 100% of the work in ⇒ 12 × 2 = 24 days

(36×2 =) 72 Person can finish 100% of the work in ⇒ \(\frac{24}{2}\) = 12 days

*Note: No. of person ∝ \(\frac{1}{time}\)
