150 students are studying English, Maths or both. 62 per cent of students study English and 68 per cent are studying Maths. How many students are studying both

Solution:

Given, 150 students are studying English, Maths or both.

62 percent of students study English

68 percent of students study Maths

We have to find the number of students studying both.

Total students = 150

Number of students studying English = 62% of 150

= (62/100) × 150

= 62 × 15/10

= 62 × 3/2

= 31 × 3

= 93

Number of students studying Maths = 68% of 150

= (68/100) × 150

= 68 × 3/2

= 34 × 3

= 102

Number of students studying English or Maths = 93 + 102

= 195

Number of students studying both = 195 - 150

= 45

Therefore, the number of students studying both is 45 students.
