A salesman visits 274 houses in a town to find out the views about three products X, Y and Z.

People who use product X = 157,

People who use only product X = 98

People who use all three product X, Y and Z = 22

People who use X and Z product but not Y = 14

People who use Y and Z product = 39

People who use only product Y = 48

Therefore,

People who use only Y and Z = people who use Y & Z – people who use all = 39 – 22 = 17

People who use only Z = all people – people who use X – people who use only Y – people who use only Y and Z = 274 – 157 – 48 – 17 = 52

People who use only X and Y

People who use only X and Y product = people who use X – people who use only X and Z – people who use only X – people who use all three = 157 – 14 – 98 – 22 = 23.

Therefore, people who used at least two products = people who used two products + people who used all products = people who used X & Y only + people who used X & Z only + people who used Y & Z only + people who used all = people who used X & Y only + people who used X & Z only + people who used Y & Z = 23 + 14 + 39 = 76.

Therefore, 76/274 fraction of total people used at least two products.
