A man is 41 year old and his son is 9 years old. In how many years will the father be three times as old as the son?
A) 3 years
B) 5 years
C) 7 years
D) 9 years
Solution: Let x = number of years until father will be 3 times as old as son.
From the statement of the problem, we get our equation:
41+x = 3(9+x)
41 + x = 27 + 3x
41 = 27 + 2x
14 = 2x
7 = x
Therefore, in 7 years the man will be three times as old as the son.\
