If 5 workers can build 2 houses in 24 days, then how many days would it take 24 workers to build 10 houses?

**A-** 10

**B-** 22

**C-** 24

**D-** 25

**E-** 60

The correct answer is D.

If 5 workers can build 2 houses in 24 days, they can make 1 house in 12 days. Therefore, each worker can make one house in 60 days. (5 × 12 = 60)

One worker can make 10 houses in 600 days. Therefore, 24 workers can make 10 houses in 25 days. (600 ÷ 24 = 25)
