A) 87 years
B) 82 years
C) 93 years
D) 95 years
E) 85 years
Correct Answer: A
Solution :
Let the age of the new man be x years. According to the question, total age of \[\text{30 men=30}\times \text{25 years}\] Again, according to the question, \[\frac{30\times 25+x}{31}=(25+2)\] Or, \[x=31\times 27-30\times 25=837-750\] \[\text{=87 years}\] Hence the age of the new man is 87 years. Logical Approach: New man's age \[=31\times 2+25=62+25=87years\]You need to login to perform this action.
