We will use the man-hour concept here to solve this problem Formula: (M1 × d1 × h1)/ W1 = (M2 × d2 × h2)/ W2 Where M, d,h, W are numbers of men, number of days, number of hours and work done respectively. Calculation: (M1 × d1 × h1)/ W1 = (M2 × d2 × h2)/ W2 ⇒ (5 × 6 × 6)/10 = (12 × d2 × 8)/16 ⇒ 18 = 6 × d2 ⇒ d2 = 3 ⇒ Number of days to make 16 toys = 3 days

Explanation

Basic rate per hour = Re. (20/40) = Re. 1/2.

Overtime per hour = 125 % of Re. 1/2 = Re.5/8.

He worked x hours overtime.

Then 20 + 5/8 x = 25 (or) = 5/8 x = 5

X = 40/5 = 8 hours

=> he worked in all for (40 + 8) = 48 hours.
