Question

According to the survey of 2000 educated unemployed persons in which 1200 were men and 800 were women, the following data were collected:

On the basis of the above table what is the difference in the number of unemployed men and women doctors?

• A. 20
• B. 30
• C. 40
• D. None of these

Answer 1

The correct option is B 30

$\frac{(12.5\times 1200)}{100}=150$ men
$\frac{(15\times 800)}{100}=120$ women.
Therefore difference = 150-120 = 30.
