Best answer
Correct Answer - Option 1 : 45

Total number of students

Number of students in Mathematics

Number of students in English

Number of students in Chemistry

Number of students in Computer

Number of students in Physics

300

45 (3/20) × 300

45

60 (45 + 15)

84 (60 + 24)

66 [300 – (45 + 45 + 60 + 84 )]

 

Number of female students in Mathematics coaching = 40% of 45

⇒ 18

Number of male students in Mathematics coaching = 45 – 18

⇒ 27

Number of female students in English coaching = 60% of 45

⇒ 27

Number of male students in English coaching = 45 – 27

⇒ 18

Total number of male students in Mathematics and English coaching = 27 + 18

⇒ 45
