CMAT Venn Diagrams Questions

Let total number of people in the town = $$100x$$

People who have both brown hair and eyes = $$b=12x$$

=> People who have brown hair = $$a+b=40x$$

=> $$a=28x$$

Similarly, $$c=18x$$

$$\therefore$$ People who have neither brown hair nor brown eyes = $$100x-(12x+18x+28x)=42\%$$

=> Ans - (D)

As can be seen from the above venn diagram distribution. Rest of the households are not reading any newspaper.

Number of households reading only one newspaper = 22 + 26 + 16 = 64.

Hence, option C.

Note: The values of the venn diagram add to 106. As it is not explicitly mentioned in the question that every household reads at least one newspaper, so remaining (120 - 106 = 14) households do not read any of the given newspaper.
