- ➜ A father's age is 10 more than his son's age
➠ Let the age of son be x and the age of father be y
❒ Therefore :
⸻ (1)

- ➜ The sum of the squares of their ages is 4 more than 3 times the product of their ages

➠ Substituting the value of y from equation (1)

❒ Using identity :









➠ x- 16 =0
➜ x = 16
➠ -x-6 = 0
➜ x = -6
❒ Age cannot be negative, hence we take the value of x as 16

- ➜ Age of son (x) = 16 yrs
- ➜ Age of father (y) = 2x +10
➜ y = (2 × 16 )+ 10
➜ y = 32 + 10
➜ y = 42 yrs
