Answer 2

Step-by-step explanation:

A product = 21 people

B product = 26 people

C product = 29 people

A and B product = 14 people

B and C product = 15 people

C and A product = 12 people

A, B and C product = 8 people

so, 1 st que ans is:

14 + 15 + 12 = 41

41 is ans

2 nd que ans is:

14 people like A and B but not C

14 is ans

3 rd que ans is:

21 + 26 + 29 = 76

76 is ans

4 th que ans is:

21 + 26 + 29 + 14 + 15 + 12 + 8 = 150

150 - 125 = 25

25 is ans
