Marks obtained by C in Science are approximately what percent of his total marks obtained in all the six subjects together ?

• A. 22
• B. 16
• C. 20
• D. 28

Answer 1

The correct option is D 28

Marks obtained by C:

History $\Rightarrow \frac{75\times 56}{100}=42$

Geography $\Rightarrow \frac{75\times 78}{100}=58.50$

Maths $\Rightarrow 71$

Science $\Rightarrow \frac{150\times 66}{100}=99$

English $\Rightarrow \frac{50\times 86}{100}=43$

Hindi $\Rightarrow \frac{60\times 70}{100}=42$

Total marks obtained = 42 + 58.5 + 71 + 99 + 43 + 42 = 355.5
$\therefore$ Required percentage $=\frac{99}{355.5}\times 100=27.85=28$
