5 . Apple juice = A

Orange juice = B

Taking neither Apple juice

nor Orange juice = 400 - n (A \cup B)

= 400 - {100 + 150 - 75}

6 . Indian food = I

Fast food = F

n (I \cup F) = 65

n (I) = 40 n (I \cap F) = 10

n (F) = ?

65 = 40 + n (F) - 10

∴ n (F) = 65 - 30 = 35

∴ only fast food = 35 - 10 = 25
