Answer 1

Step-by-step explanation:

the ratio of present ages of Suresh and Mahesh is 5:7

so Suresh/Mahesh = 5/7................(1)

after 4 years their age will be 3:4

so subtract 6 from the above ratio to change to present age

then Suresh/Mahesh = (3x -4)/(4x - 4)...........(2)

equate (1) and (2)

5/7 = (3x - 4)/(4x - 4)

5(4x - 4) = 7(3x - 4)

20x-20 = 21x - 28

-20+28=21x-20x

8 =x

x =8

now you can do it you self
