In a group of 17 people 10 are men and rest are boys. It is said that the men have twice capacity to do a work as compared to boys. If boys do a total of 37 units of work, what is the average work done by 7men and 25 boys? Find the answer to the closest integer.

Correct Answer: 45
Work done by 1 boy = 37 units Work done by 1 man = twice of work done by a boy = 37 * 2 = 74 units Total work done by 7 men = 74 * 7 = 518 Total work done by 25 boys = 25 * 37 = 925 Total work done = 1443 Average work done = 1443 / 32 = 45.09 ≈ 45
