MARK ME BRAINLIEST.
Step-by-step explanation:
present age = 2:3
age after 3 years = 5:7
Anu's age = 2x+3=5x
Hari's age = 3x+3=7x
ratio= (2x+3)/(3x+3)=5x/7x
=2x+3=5*3x+3/7
=2x+3=15x+15/7
=2x=15x+15-21/7
14x=15x+15-21
14x-15x=15-21
21-15=15x-14x
6=x
x=6.
sbstituting value of
Anu's present age = 2x = 2*6 = 12
Hari's present age = 3x = 3*6 = 18
