Q. G is 3 years older than H. If the sum of their ages is 45 years, how old is H?
A.
20
B.
21
C.
22
D.
23
Solution
Let H's age be x. Then G's age is x + 3. So, x + (x + 3) = 45. Solving gives x = 21.
Q. If a mother is 6 times as old as her daughter now, and in 6 years, she will be 4 times as old as her daughter, how old is the daughter now?
A.
6
B.
4
C.
5
D.
3
Solution
Let the daughter's age be x. Then the mother's age is 6x. In 6 years, the mother will be 6x + 6 and the daughter will be x + 6. The equation is 6x + 6 = 4(x + 6), which simplifies to 6x + 6 = 4x + 24, so 2x = 18, and x = 9.
Q. If the present age of a father is 45 years and his son is 15 years old, in how many years will the father be twice as old as his son?
A.
10
B.
15
C.
20
D.
5
Solution
Let the number of years be x. In x years, the father's age will be 45 + x and the son's age will be 15 + x. The equation is 45 + x = 2(15 + x), which simplifies to 45 + x = 30 + 2x, so x = 15.
Q. If the present age of a grandfather is 80 years and the age of his grandson is 20 years, how many years ago was the grandfather 3 times as old as the grandson?
A.
10
B.
20
C.
30
D.
40
Solution
Let x years ago, grandfather's age was 80 - x and grandson's age was 20 - x. We need 80 - x = 3(20 - x). Solving gives x = 10.
Q. If the present age of a man is 4 times that of his son, and after 5 years, the man will be 3 times as old as his son. What is the present age of the son?
A.
5
B.
10
C.
15
D.
20
Solution
Let the son's age be x. Then the man's age is 4x. In 5 years, 4x + 5 = 3(x + 5). Solving gives x = 10.
