Question 1
Vijay is twice as old as Deepa was 7 years ago. The difference between their ages is 3 years. How old is Vijay?
Let Deepa's current age = x
Then 7 years ago, Deepa was (x - 7)
Vijay = 2(x - 7) = 2x - 14
Difference: Vijay - x = (2x - 14) - x = x - 14
Given difference = 3
So x - 14 = 3 → x = 17 = 17
Then Vijay = 2(17 - 7) = 20
Then 7 years ago, Deepa was (x - 7)
Vijay = 2(x - 7) = 2x - 14
Difference: Vijay - x = (2x - 14) - x = x - 14
Given difference = 3
So x - 14 = 3 → x = 17 = 17
Then Vijay = 2(17 - 7) = 20
