A) 36 yr and 40 yr
B) 32 yr and 48 yr
C) 40 yr and 56 yr
D) 36 yr and 56 yr
Correct Answer: B
Solution :
Four years ago let the age of A and B be 2x and 3x yr respectively. According to the question, \[\frac{2x+8}{3x+8}=\frac{5}{7}\] \[\Rightarrow \] \[14x+56=15x+40\] \[\Rightarrow \] \[x=16\] Present age of A = 2x \[=2\times 16=32\,yr\] Present age of B = 3x \[=3\times 16=48\,yr\]You need to login to perform this action.
