The current age of Mike is four that of Nancy. 3 years
from now, Mike's age will be two times the age of Owen at that time. If Nancy is 6 years younger than Owen, determine the current age of Mike.Solution
Let the present age of Nancy be ‘n’ years. Thus, the present age of Mike = ‘4n’ years. Let the present age of Owen be ‘n + 6’ years. ATQ, (4n + 3) = 3 × (n + 6 + 3), Or, 4n + 3 = 3n + 27, Or, 4n – 3n = 27 - 3, Or, n = 24 Therefore, 4n = 96. Therefore, the current age of Jerry = 96 years
