Answer 1

root x+20 is the answer

Answer 2

Answer:

45 years

Step-by-step explanation:

According to question, from 1960 to x^2 years, the age of Shri Pankajbhai will be x+20 years. i.e.,

x^2 - 1960 = x + 20

x^2 - x - 1980 = 0

x^2 - (45-44)x - 1980 = 0

x^2 - 45x + 44x - 1980 = 0

x(x - 45) + 44(x-45) = 0

(x-45)(x+44) = 0

x = 45 or x = -44

But age can't be negative

So, x = 45.
