Medium
In a joint family there are a father, mother, 3 married sons and one unmarried daughter. Two of the sons have two daughters each and one son has one son. How many female members are there in the family?
Explanation
Explanation
Female members: mother (1) + unmarried daughter (1) + two daughters of each of two sons (2×2=4) = 1+1+4 = 6. The third son's child is a son, not a daughter. Therefore, the total is 6.
