Discussion

Explanation:

There are 240 students in all, out of which 59 do not study any subject out of the given three.

∴ 181 study one or more of Financial Derivatives (FD), Behavioral Finance (BF) and Security Analysis (SA).

No. of students who study both FD and SA but not BF

= 4 × no. of students who study all three = 4 × 4 = 16

= 2 × no. of students who study both FD and BF but not SA

Also, no. of students who study both FD and SA but not BF = no. of students who study both BF and SA = 16

∴ We have the following:

​​​​​​​

∴ No. of students who study only BF

= 181 – 124 – 20 – 8 = 29

Hence, option (a).
