In a coaching institute, there are 300 students. \(\frac{3}{20}\) of the total number of students are enrolled in Mathematics coaching. The number of students enrolled in English coaching is the same as the number enrolled in Mathematics coaching. The number of students enrolled in Chemistry coaching is 15 more than the number enrolled in English coaching. The number of students enrolled in Computer coaching is 24 more than the number enrolled in Chemistry coaching. The remaining students are enrolled in Physics coaching. If 40% of the students enrolled in Mathematics and 60% of the students enrolled in English are female students, then find the total number of male students enrolled in Mathematics and English together.

1. 45
2. 27
3. 18
4. 23

Correct answer: 45

Solution

Mathematics students = \(\frac{3}{20} \times 300 = 45\). English students are also 45. Female students in Mathematics = 40% of 45 = 18, and in English = 60% of 45 = 27. So male students together = \((45-18) + (45-27) = 27 + 18 = 45\).
