The average number of students qualified in the examination from Schools C and D is what percent of the average number of students appeared for the examination from the same schools? (rounded off to 2 digits after decimal)

A) 58.62

B) 73.91

C) 62.58

D) 58.96

E) None of these

Answer:

Option B

Explanation:

Average number of students qualified from C and D

= $\frac{1}{2}$ (2250+2000) = $\frac{4250}{2}$ = 2125

Average number of students appeared from C and D

= $\frac{1}{2}$ (3250+2500) = $\frac{5750}{2}$ = 2875

Required% = $\left(\frac{2125}{2875}\times100\right)$ %

= $\frac{1700}{23}$ % = 73.91%
