Both F and A work in the same department but at different posts. Both A and D work at different posts. The sum of the ages of C and G is 64 years. Both C and D are younger and work in different departments, but not in production. E is 12 years older than F and 12 years younger than H. The difference between the ages of C and D is equal to H’s age. B is 30 years old and his age is half of H’s age. How many persons are working as manager?

Four
Five
Three
Two

Correct answer: Three

Solution

From B = 30 and B being half of H, H = 60. Then E = 48 and F = 36; using the age relations for C and D gives the remaining ages consistently. After assigning posts with the given constraints, exactly three persons are managers.
