D) Cannot be determined

E) None of these

Answer:

Option D

Explanation:

Number of students who opted for the given three subjects in the year 2009 is

(20000 + 20000 + 5000) = 45000.

Number of girls = 38% of 45000

= $\frac{38}{100}\times45000$ = 17100

Out of these, the number of boys who opt for Mathematics cannot be found.
