Answer» Correct Answer - Option 3 : 40 Given A certain number of men could do a piece of work in 60 days With 8 more men, it could be finished in 50 days Formula used m1 × d1 = m2 × d2 Where, m = number of men and d = number of days Calculation Let the number of men initially was 'x' ⇒ x men can do a piece of work in 60 days And x + 8 men can finish the work in 50 days ⇒ x × 60 = (x + 8)× 50 ⇒ 60x = 50x + 400 ⇒ 10x = 400 ⇒ x = 40 ∴ The number of men in the beginning was 40 |
