Question 1
Sagar is 3 times as old as his son Freya. After 3 years, the sum of their ages will be 70. How old is Freya now?
Let son's age = x, then father's age = 3x
After 3 years: (3x+3) + (x+3) = 70
(3+1)x + 6 = 70
(4)x = 64
x = 16
After 3 years: (3x+3) + (x+3) = 70
(3+1)x + 6 = 70
(4)x = 64
x = 16
