5. AGE
4) The sum of ages of 5 children
born at the intervals of 3 years
each is 50 years. What is the age
of the youngest child?
a. 4 years b. 8 years
c. 10 years d. 6 years
Answer: a

6. Explanation
Let the ages of children be x, (x + 3), (x +
6), (x + 9) and (x + 12) years.
Then, x + (x + 3) + (x + 6) + (x + 9) + (x +
12) = 50
5x = 20
x = 4.
Age of the youngest child = x = 4 years.

7. AGE
5) A is two years older than B who
is twice as old as C. If the total of
the ages of A, B and C be 27, the
how old is B?
a. 7 b. 8
c. 9 d. 10
Answer: d

8. Explanation
Let C's age be x years. Then, B's age =
2x years. A's age = (2x + 2) years.
(2x + 2) + 2x + x = 27
5x = 25
x = 5.
Hence, B's age = 2x = 10 years.

9. AGE
6) A man is 24 years older than his
son. In two years, his age will be
