If you are asking for the solutions. .these are real easy questions plz try first. .

Let the supermarkets are S1 and S2
S1 U S2 = 150
And S1 ∩ S2

Q1. 185 – 150 = 35

Q2. 150 – 10 =140

etc
 

answer for question 4 is wrong. It must be 105. becz no of families who dont visit G will be = no of families who dont visit any super market+ no of families who visit S only.= 35+70 = 105
