# Difficult Pie Charts Solved QuestionData Interpretation Discussion

Common Information

The following pie charts show the results of a survey among employed men in a colony.

Total population is 7,200.

 Q. Common Information Question: 5/5 At least what percentage of the men were less than 75 years of age and are neither engineers nor doctors?
 ✖ A. 10 ✖ B. 20 ✖ C. 25 ✔ D. 30 ✖ E. 40

Solution:
Option(D) is correct

Men who were of age 75 years or above = 20%

Men who were either Doctors or Engineers:

$= 100 + 80$

$=180°$

$= 50\%$

⇒ The maximum number of people in the given categories:

$= 20\% + 50\%$

$= 70\%$ (when none of the Doctors or Engineers is 75 or above}.

At least $100 - 70 = \textbf{30%}$ of the men were less than 75 years of age and neither doctors nor engineers.

Total=7200

Above 75 =20% =1440

Let all engineers and doctors are in this group.total doc and eng= 50%=3600

3600-1440=2160...these are doc and eng less than 75 yrs of age.

7200-1440=5760= total people less than 75

5760-2160=3600 are no of people less than 75 and neither doc nor eng=50%
