Question

In a school there are 80% students passed in mathematics and 90% students passed in English. No one failed in both subject. If there are 210 students passed in both subject then find out how many students are there in the school?​

Answer 1

Answer:

100% (all students who took the test).

Since 0% failed in both, then 100% students are to be discussed.

Since 90% passed in English, 85% passed in Math and 150 students passed in both

Then, failed in English = (100% - 90%) = 10%.

Failed in Math = (100% - 85%) = 15%.

So total % of students failed = failed in both subjects + failed in English + failed in Math = 0% + 10% + 15%

= 25%.

So passed in both subjects = 100% - 25% =75%.

Answer: In that exam 75% passed in both subjects.

75% of students = 150

100% of students = 150*100/75 = 200 students
