A) 21 years
B) 24 years
C) 30 years
D) 40 years
Correct Answer: C
Solution :
Let Maya's present age be \[6x\] years and Chhaya's present age be \[5x\] years. After 15 years, \[\frac{6x+15}{5x+15}=\frac{9}{8}\] \[\Rightarrow \] \[48x+120=45x+135\] \[\Rightarrow \] \[48x-45x=135-120\] \[\Rightarrow \] \[3x=15\Rightarrow x=5\] \[\therefore \]Maya?s present age\[=6x\] \[=6\times 5=30\]yearsYou need to login to perform this action.
