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.
