Correct Answer: 390%


Solution : The total number of girls in all these six schools is 9000
Number of girls in school D = 39% of 9000 $=\frac{39}{100}\times9000 = 3510$
Number of girls in school I = 10% of 9000 $=\frac{10}{100}\times 9000 = 900$
$\therefore$ Required percentage = $\frac{\text{No. of girls in school D}}{\text{No. of girls in school I}}\times 100=\frac{3510}{900}\times 100= 390$%
Hence, the correct answer is 390%.
