Question 1
Ines is 3 times as old as his son Pawan. After 8 years, the sum of their ages will be 72. How old is Pawan now?
Let son's age = x, then father's age = 3x
After 8 years: (3x+8) + (x+8) = 72
(3+1)x + 16 = 72
(4)x = 56
x = 14
After 8 years: (3x+8) + (x+8) = 72
(3+1)x + 16 = 72
(4)x = 56
x = 14
