What are the average marks in percentage obtained by Mohan?
Option 1: 70.6%
Option 2: 74.6%
Option 3: 73.2%
Option 4: 73.6%
Correct Answer: 73.6%
Solution :
Mohan's marks in Chemistry = 300 × $\frac{70}{100}$ = 210
Mohan's marks in Mathematics = 300 × $\frac{75}{100}$ = 225
Mohan's marks in Physics = 150 × $\frac{80}{100}$ = 120
Mohan's marks in Hindi = 300 × $\frac{65}{100}$ = 195
Mohan's marks in English = 200 × $\frac{85}{100}$ = 170
Mohan's total marks = 210 + 225 + 120 + 195 + 170 = 920
Total marks in the examination = 300 + 300 + 150 + 300 + 200 = 1250
$\therefore$ Mohan's overall percentage = $\frac{920}{1250}$ × 100 = 73.6%
Hence, the correct answer is 73.6%.
