Hello friend
Good morning
Given that the present ages of Anu and Ajay are in ratio 7:9
Let their present ages be 7x and 9x.
According to the question, 9 years ago their age was 2:3
Therefore 7x-9/9x-9 = 2/3
=> 3(7x-9) = 2(9x-9)
=> 21x - 27 = 18x - 18
=> 21x - 18x = -18 + 27
=> 3x = 9
=> x = 9/3
=> x = 3
Hence, present age of Anu = 7x
= 7 × 3
= 21 years
Present age of Ajay = 9x
= 9 × 3
= 27 years
I hope it will help you..
