 A) 28 B) 36 C) 48 D) 52

 B) 36

12 men can do the work in 24 days.

Therefore, 1 man will do it in $$\Large \frac{24 \times 12 }{8}$$ days

Therefore, 8 men will do it in $$\Large \frac{24 \times 12 }{8}$$ days

Therefore, Required number of days = $$\Large \frac{24 \times 12 }{8} = 3 \times 12$$ = 36 days
