Hiii!!!
Here's Ur answer...
Given the ratio between the age of Reena and Teena is 3 : 4
Let their age be 3x and 4x respectively.
5 years ago, the ratio between their age was 2 : 3
Therefore 3x - 5/ 4x - 5 = 2/3
==> 3 ( 3x - 5 ) = 2 ( 4x - 5 )
==> 9x - 15 = 8x - 10
==> 9x - 8x = -10 + 15
==> x = 5
Hence, present age of Reena = 3x
= 3 × 5
= 15yrs
Present age of teena = 4x
= 4 × 5
= 20yrs
Hope this helps..!!
