Answer:
22 is the answer because:-
Step-by-step explanation:
If we add up all ages now we will get 25*7=175
So 175 - 3*7 =154/7 =22
But we don’t know if some one died in these 3 years and someone is born in these 3 years
If someone is born last year and her age is 1 now
a+b+c+d+e+f+1=175
So before 3 years Average = (174 -18)/6 = 26
So answer is 22 if none is born or died in last 3 years.
