- A. 24
If present age of Raj=5x and Anu =4x
After 3 years ratio becomes,(5x+3)/(4x+3)=11/9 or 45x+27=44x+33,x=6
So present age of Anu=4*6= 24 years - 11 years agoHelpfull: Yes(2) No(0)
- let present age of raj be 5x and anu be 4x.
then after 3 year age of raj is 5x+3 and age of anu is 4x+3
and the ratio of their ages will become 11:9
=>(5x+3)/(4x+3)=11/9
on solving we get x=6
=>age of anu =4x=4*6=24 - 11 years agoHelpfull: Yes(1) No(1)
- Let the present age of raj and anu are 5x and 4x respectively.
3years hence their ages become (5x+3) and (4x+3) respectively..
So that (5x+3)/(4x+3)=11/9.
After solving we get x=6.
So anu's present age is 4*6=24.
