The total number of students who have enrolled for the course on Coco SD from colleges P and R together is what percent more than the total number of students who have enrolled for the same course from college S?

A) \( 11\frac{10}{17} \%\)
B) \( 11\frac{4}{17} \% \)
C) \( 12\frac{9}{11} \% \)
D) \( 10\frac{10}{19} \% \)
E) \( 9\frac{10}{19} \% \)

Correct Answer:




D) \( 10\frac{10}{19} \% \)

Description for Correct answer:

Total number of students enrolled in Coco SD course from college P and R

= \( \frac{21}{100} \times 2800+\frac{21}{100} \times 2800 \)

= 588 + 588 = 1176

Total number of students enrolled in same courses from college S

= \( \frac{38}{100} \times 2800 \) = 1064

Increased percentage

= \( \left( \frac{1176-1064}{1064} \times 100 \right) \)%

= \( 10 \frac{10}{19} \)%
