A) 56 yr
B) 32 yr
C) 42 yr
D) 48 yr
Correct Answer: D
Solution :
Let Present ages of Vikky and Sumi are 2 x yr and 3x yr, respectively then Given, \[\frac{(2x+12)}{(3x+12)}=\frac{11}{15}\] \[\Rightarrow \] \[30x+180=33x+132\] \[\Rightarrow \] \[(33-30)x=180-132\] \[\therefore \] \[x=\frac{48}{3}=16\] \[\therefore \] Present age of Sumi\[=3x=3\times 16=48\,\,yr\]You need to login to perform this action.
