Posted on 24-12-2022
Ques - Abhinav scores 80% in physics and 66% in chemistry and the maximum marks of both the papers are 100. what percent does he score in maths which is of 200 marks, if he scores 80% marks in all the three subjects:
(a) 74%
(b) 84%
(c) 87%
(d) 83%
Solution - Maximum marks in physics = 100
Abhinav scores in physics = 80% of 100
= (80/100) × 100
= 80
Maximum marks in chemistry = 100
Abhinav scores in chemistry = 66% of 100
= (66/100) × 100
= 66
Maximum marks in Maths = 200
Total maximum marks in all three subjects = 100 + 100 + 200
= 400
Abhinav scores in all three subjects = 80% of 400
= (80/100) × 400
= 320
Abhinav scores in all three subjects = 320
Abhinav scores in physics and chemistry = 80 + 66
= 146
Abhinav scores in maths = 320 - 146
= 174
Abhinav scores in maths in percentage = (174/200) × 100
= 174/2
= 87
Hence,
Abhinav scores in maths in percentage is (c) 87%.
