A) \[36\,\,yr\]
B) \[34\frac{5}{6}\,yr\]
C) \[35\frac{4}{5}\,yr\]
D) None of these
Correct Answer: B
Solution :
3 yr ago, total age of 5 members \[=5\times 35=175\,\text{yr}\] At the time of birth of new baby the total age of family \[=175\,+\,(2\times 5)=185\,yr\] The present age of family \[=185+\,(1\times 6)=191\,yr\] 3 yr, hence the average age of family \[=\frac{191+(3\times 6)}{6}\] \[=34\frac{5}{6}yr\]You need to login to perform this action.
