Question

at present wasim age is more 5 than the square of her son zayn age . when zayn his fathers present age, wasim age would be sixteen years more than 10 times of the present age. find the present age of both wasim and zayn

Answer 1

Answer: Zayn 6 years and Wasim 41 years

Step-by-step explanation:

Let Zayn's present age be x. Then present age of Wasim is x²+5

Zayn becomes his father's age in x²+5-x years. Then Wasim's age will be x²+5+x²+5-x = 2x²-x+10

Given, when zayn his fathers present age, wasim age would be sixteen years more than 10 times of the present age

This means,  2x²-x+10=10x+16

⇒2x² - 11x -6 =0

⇒(2x+1)(x-6)=0

⇒x= -1/2 or 6

⇒x=6 as age cant be negative.

So present age of Zayn is 6 and present age of Wasim is 41
