Question 1
6 years ago, the ratio of Piya's age to Sarabjit's age was 3:5. 12 years from now, the ratio will be 2:3. Find Piya's present age.
Let Piya's present age = x, Sarabjit's present age = y
6 years ago: (x-6)/(y-6) = 3/5
12 years from now: (x+12)/(y+12) = 2/3
Solving these equations gives x = 18, y = 30
6 years ago: (x-6)/(y-6) = 3/5
12 years from now: (x+12)/(y+12) = 2/3
Solving these equations gives x = 18, y = 30
