Question
The current age of Lisa is three times that of Maya. 5
years from now, Lisa's age will be twice the age of Tom at that time. If Maya is 3 years younger than Tom, determine the current age of Lisa.Solution
Let the present age of Maya be ‘a’ years. Thus, the present age of Lisa = ‘3a’ years. Let the present age of Tom be ‘a + 3’ years. ATQ, (3a + 5) = 2 × (a + 3 + 5), Or, 3a + 5 = 2a + 16, Or, 3a – 2a = 16 - 5, Or, a = 11, Therefore, 3a = 33 Therefore, a +3 = 11 + 3 = 14 Therefore, the current age of Lisa = 3a = 33 years.
