Question

present ages of Rohit and Mayank are in the ratio 11:8.8 years hence ratio of their ages will be 5:4 .Find their present ages

Answer 1

let their present age =x
so age of Rohit. =11x
age of mayank. =8x
8year hence............
according to question=11x+8/8x+8=5/4
=4(11x+8)=5(8x+8)
=44x+32=40x+40
=44x-40x=40-32
=4x=811
=x=8/4=2
so age of Rohit=11x.
=11*2=22yrs
age of mayank=8x
=8*2=16yrs
