Question 1
Manmohan is twice as old as Hailey was 4 years ago. The difference between their ages is 21 years. How old is Manmohan?
Let Hailey's current age = x
Then 4 years ago, Hailey was (x - 4)
Manmohan = 2(x - 4) = 2x - 8
Difference: Manmohan - x = (2x - 8) - x = x - 8
Given difference = 21
So x - 8 = 21 → x = 29 = 29
Then Manmohan = 2(29 - 4) = 50
Then 4 years ago, Hailey was (x - 4)
Manmohan = 2(x - 4) = 2x - 8
Difference: Manmohan - x = (2x - 8) - x = x - 8
Given difference = 21
So x - 8 = 21 → x = 29 = 29
Then Manmohan = 2(29 - 4) = 50
