A student gets 60, 50 and 90 marks out of 100 in English, Physics and Economics respectively. He needs 72% to get a scholarship How many marks does he need to get in his final paper Math's to obtain overall 72% marks?
- 84
- 82
- 88
- 86
Explanation
60 (English) + 50 (Physics) + 90 (Economics) = 200
Total marks possible so far = 3 x 100 = 300
Now, let's calculate the total marks required to get 72% overall:
Total marks required = 72% of (300 + 100) (assuming Math's paper has 100 marks)
= 0.72 x 400
= 288
Now, let's subtract the marks already obtained from the total marks required:
288 - 200 = 88
So, the student needs 88 marks in Math's to obtain overall 72% marks.
