Correct Answer: D
$ \therefore $ Total number of students for Coco SD from college P and R $ =588+588=1176 $ Number of students for Coco SD from college S $ =2800\times \frac{38}{100}=1064 $
$ \therefore $ Required percentage $ =\frac{1176-1064}{1064}\times 100% $ $ =\frac{112\times 100}{1064}=\frac{112\times 25}{266}=\frac{56\times 25}{133} $ $ =\frac{8\times 25}{19}=\frac{200}{19}=10\frac{10}{19}% $
