Average age of 8 men is increased by 3 years when two of them whose age are 30 and 34 years are replaced by 2 persons. What is the average age of the 2 persons ?
Answer & explanation
Correct answer: option 3
Per head increase = 3 years
Total increase = 8×3= 24 years
this means the two new men ,who have replaced the other two men , are carrying 24 years more than the sum of the ages of the men with ages 30 and 34 years i.e. (30+34 = 64)
So the Sum of the ages of the two new men = 64 + 24 = 88
Therefore Average age of two new men = \(\frac{88}{2}\)= 44
