How many bowls does he need?a) 27b) 14c) 8d) 12

Answer 1

Grand total of all the people is A) 27

Answer 2

The correct answer is option c - 8

one grandfather and one grandmother =  2

2 fathers and 2 mothers include grandfather and grandmother. So, total = 4.

 5 children include 1 set of father and mother, along with 3 children. 4 grandchildren include the 3 children also. The 3 sisters, 1 brother, 3 daughters 2 sons, can be the children and the grandchildren. 1 mother-in-law and 1 father-in-law can be the grandparents. Either of the parent, children, or grandchildren could be a daughter-in-law.

So, by canceling out the common relationships, the total number comes to 8 members.
