Answer 2

Answer:

Let the present age of Rahul be X present age of Vikas be Y.

Case 1

(x-4) /(y-4) = 3/5

by cross multiplication

5(x-4) = 3(y-4)

5x-20 = 3y-12

5x-3y= -12+20

5x-3y= 8. ........(1)

Case 2

(x+6)/(y+6)= 4/5

by cross multiplication

5(x+6)=4(y+6)

5x+30= 4y+24

5x-4y= 24-30

5x-4y= -6. ..........(2)

From (1)

5x=8+3y

x=8+3y/5. ..........(3)

Substituting (3) in (2)

5(8+3y/5)-4y = -6

Then 5 and 5 will be cut as it is in division

8+3y-4y=-6

8-y= -6

-y= -6-8

-y= -14

y= 14

Putting y=14 in (1)

5x-3(14)=8

5x-42=8

5x=8+42

5x=50

x=50/5

x=10

So,the age of Rahul (X) =10

age of Vikas (y) = 14.
