Question

please send me full solution !!!

Answer 1

Let Present age of vijay be x and of sushma be y yrs

We are given, y = x + 15 .............................(1)
 and,    (y + 3) = 8(x-3)
            
         By Putting value of y from Eqn (1)

        x + 15 + 3 = 8x - 24
             7x = 42
 so, x = 6 

Hence Present Age of Vijay = 6 Yrs.
And Of Sushma = 21 yrs. 
             

Answer 2

Let the present age of Sushma be x.

Let the present age of Vijay be y.

Given that Sushma is now 15years older than Vijay.

x = y + 15.  ------- (1)


Given that in 3 years more she will be 8 times as old as vijay was 3 years ago.

x + 3 = 8(y - 3)

x + 3 = 8y - 24

y + 15 + 3 = 8y - 24

y + 18 = 8y - 24

7y = 42

y = 6.

Substitute y = 6 in (1), we get

x = 6 + 15

x = 21.


Therefore the present age of Sushma is 21 years.

Therefore the present age of Vijay is 6 years.


Verification:

x = y + 15

x - y = 15

21 - 6 = 15

15 = 15.


Hope this helps!
