The ratio of men to women in each Specialization.

IT 1 2
Finance 5 4

 

4.1) What is the total number of men studying in the Institute?

(a) 1665
(b) 2421
(c) 2025
(d) 1954

Solution:   Ans:- B

First we have to calculate men and women from the pie chart and table for each specialization. It becomes easy to answer other questions also.

Specialization Men Women Total
HR 396 594 990
Marketing 720 420 720
International Business 675 135 810
Banking 340 200 540
IT 315 630 945
Finance 275 220 495
2421 2079 4500

Number of students in HR
Number of men in HR = 2/5 ×22/100 ×4500 = 2×22×9 = 396.
The number of women in HR = 3/5 ×22/100 ×4500 =594. (This way we have to calculate for each specialization).

From the above, the answer is 2421.
