A) 48 yr
B) 26 yr
C) 44 yr
D) 28 yr
Correct Answer: A
Solution :
Let the ages of A and B four years ago be 11x and 14x yr respectively. According to the question, After 4 yr \[\frac{11x+8}{14x+8}=\frac{13}{16}\] \[\Rightarrow \] \[176x+128=182x+104\] \[\Rightarrow \] \[182x-176x=128-104\] \[\Rightarrow \] \[6x=24\] \[\Rightarrow \] \[x=\frac{24}{6}=4\] \[\therefore \] A's present age \[=(11x+4)\,yr\] \[=11\times 4+4=48\,yr\]You need to login to perform this action.
