Question

one year ago a man was 8 times as old as his son. now, his age is equal to the square of his son's age. find their pres ent age​

Answer 1

Answer:

Let the present age of the son be x years. It is given that one year ago; a man was 8 times as old as his son. If x = 1, then x2 = 1, which is not possible as father's age cannot be equal to son's age. So, x = 7.

Answer 2

Step-by-step explanation:

Let x be the age of the son one year ago, then the age of the man was 8x.

The present age of the son is (x+1) and that of the man is (8x+1). Then,

8x+1=(x+1)2

8x+1=x2+1+2x

x=0,6

As the age cannot be 0, so the value of x is 6.

So, present age of son =(x+1)=7 years

and Present age of man =(8x+1)=48 years
