Concept: The question tests on Average
Solution:
Let the average of the original 7 men = x
Sum of ages = 7x
Now, from this sum, 2 ages of 22 and 26 are removed and 2 new ages (say a and b)
The new sum of ages = 7x - 22 - 26 + a + b = 7x - 48 + a + b
The new average = x + 2
Therefore 7x−48+a+b7=x+27x−48+a+b7=x+2
7x - 48 + a + b = 7x + 14
a + b = 62
Average = (a + b)/2 = 62 / 2 = 31 years
