Question 1
Swati is twice as old as Sneha was 3 years ago. The difference between their ages is 28 years. How old is Swati?
Let Sneha's current age = x
Then 3 years ago, Sneha was (x - 3)
Swati = 2(x - 3) = 2x - 6
Difference: Swati - x = (2x - 6) - x = x - 6
Given difference = 28
So x - 6 = 28 → x = 34 = 34
Then Swati = 2(34 - 3) = 62
Then 3 years ago, Sneha was (x - 3)
Swati = 2(x - 3) = 2x - 6
Difference: Swati - x = (2x - 6) - x = x - 6
Given difference = 28
So x - 6 = 28 → x = 34 = 34
Then Swati = 2(34 - 3) = 62
