उत्तर
Given, total students in the class studying English, Maths or both = 150
Students studying English = 62% of 150 = `62/100 xx 150` = 93
Students studying Maths = 68% of 150 = `68/100 xx 150` = 102
Total students studying both = Students studying English + Students studying Maths – Students studying English Maths or both
= 93 + 102 – 150
= 45
