hiii!!!
here's Ur answer...
given the present ages of Madhu and Madhuri is 5 : 9
ATQ, after 3 years their age will be in the ratio 2 : 3
let their present ages be 5x and 9x respectively.
therefore 5x + 3/ 9x + 3 = 2/3
==> 3 ( 5x + 3 ) = 2 ( 9x + 3 )
==> 15x + 9 = 18x + 6
==> 9 - 6 = 18x - 15x
==> 3 = 3x
==> x = 3/3
==> x = 1
hence, present age of Madhu = 5x = 5 × 1 = 5yrs
present age of Madhuri = 9x = 9 × 1 = 9yrs
hope this helps..!!
