Answer 1

Answer:

250

Step-by-step explanation:

Percentage of students took Science  = 72%

Percentage of students took Mathematics = 44%

Percentage of students took both subjects = (72 + 44) - 100 = 16%.

But is given 40 students have taken both the subjects.

=> 16% of total students = 40

=> Total number of students = 40 * 100/16 = 250
