Question 67

Study the following table and answer the question:
Percentage of marks obtained by six students A, B, C, D, E and F in five subjects.

The total marks obtained by student F in English, Science and Hindi is approximately what percent of the total marks obtained by student A in English, Mathematics, Science and Hindi? (Correct to one decimal place)

Solution

The total marks obtained by student F in English, Science and Hindi = $$\frac{72}{100}\times50+\frac{60}{100}\times80+\frac{60}{100}\times75$$ = 36 + 52 + 45 = 133

The total marks obtained by student A in English, Mathematics, Science and Hindi = $$\frac{70}{100}\times50+\frac{90}{100}\times150+\frac{60}{100}\times80+\frac{64}{100}\times75$$ = 35 + 135 + 52 + 48 = 270

Required percentage = $$\frac{133}{270}\times100$$

= 49.259%

= 49.3% (approximately)

Hence, the correct answer is Option B
