What are the approximate percentage marks obtained by student T in all subjects together?
Option 1: 65
Option 2: 58
Option 3: 47
Option 4: 52
Correct Answer: 58
Solution :
T's marks in Physics = $80×\frac{65}{100}=52$
T's marks in Mathematics = $150×\frac{60}{100}=90$
T's marks in Hindi = $100×\frac{45}{100}=45$
T's marks in Geography = $75×\frac{88}{100}=66$
T's marks in English = $120×\frac{50}{100}=60$
T's marks in History = $50×\frac{42}{100}=21$
T's total marks = 52 + 90 + 45 + 66 + 60 + 21 = 334
Total marks in the examination = 80 + 150 + 100 + 75 + 120 + 50 = 575
$\therefore$ Percentage = $\frac{334}{575}×100=58.09\approx58$%
Hence, the correct answer is 58.
