Ratio of the age of A after 4 years and the age of B after 3 years is 8:9 and the present age of C is 25% less than the present age of A. If A is 6 years younger than B, then find the age of C 5 years hence?
a) 36 years
b) 40 years
c) 25 years
d) 32 years
e) None of these
Sol:
B-A=6
The present age of A=(8x-4)
The present age of B=(9x-3)
(9x-3)-(8x-4)=6
x+1=6
x=5
The present age of A=8*5-4=36 years
The present age of C=36*75/100=27 years
After 5 years, the age of C=27+5=32 years
