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