Question 1
Pooja is twice as old as Yara was 7 years ago. The difference between their ages is 12 years. How old is Pooja?
Let Yara's current age = x
Then 7 years ago, Yara was (x - 7)
Pooja = 2(x - 7) = 2x - 14
Difference: Pooja - x = (2x - 14) - x = x - 14
Given difference = 12
So x - 14 = 12 → x = 26 = 26
Then Pooja = 2(26 - 7) = 38
Then 7 years ago, Yara was (x - 7)
Pooja = 2(x - 7) = 2x - 14
Difference: Pooja - x = (2x - 14) - x = x - 14
Given difference = 12
So x - 14 = 12 → x = 26 = 26
Then Pooja = 2(26 - 7) = 38
