3. In the youth summer village there are 150 people, 75 of them are not working, 50 of them have families and 100 of them like to sing in the shower. What is the largest possible number of people in the village, which are working, that doesnâ€™t have families and that are singing in the shower?
25.
50.
75.
100.
150.

thers are 50 ppl with families , since we are trying to find ppl with no families we will have to exclude them. . Now we are left with 150- 50 = 100 ppl

now assuming all the 75 ppl working have no family and assume all 75 take shower the max number to satisfy the required cond is 75
