Total population is 7,200.

 Q. Common Information Question: 4/5 If all the engineers were of age less than 45 years, then at least what percentage of the engineers were of age 35 or above and less than 45 years.
 ✔ A. 10 ✖ B. 15 ✖ C. 20 ✖ D. 30 ✖ E. 40

Solution:
Option(A) is correct

Percentage of engineers:

$= \dfrac{80}{360}×100$

$= 22.22\%$

Almost 20% can be less than 35.

⇒ At least 2.22%

i.e., $\dfrac{2.22}{22.22}× 100 = \textbf{10%}$ of engineers were of age 35 or above and less than 45 years.
