Answer: Option B. -> 30%
Number of students enrolled in various streams:
$$\eqalign{
& \text{IT → } \frac{20}{100}\times3500 = 700 \cr
& \text{Arts → } \frac{30}{100}\times3500 = 1050 \cr
& \text{Science → } \frac{22}{100}\times3500 = 770 \cr
& \text{Commerce → } \frac{12}{100}\times3500 = 420 \cr
& \text{Management → } \frac{16}{100}\times3500 = 560 \cr} $$
Number of girls enrolled in various streams:
$$\eqalign{
& \text{IT → } \frac{18}{100}\times1500 = 270 \cr
& \text{Arts → } \frac{38}{100}\times1500 = 570 \cr
& \text{Science → } \frac{11}{100}\times1500 = 165 \cr
& \text{Commerce → } \frac{21}{100}\times1500 = 315 \cr
& \text{Management → } \frac{12}{100}\times1500 = 180 \cr} $$

Required percentage
$$\eqalign{
& = \left(\frac{1050}{3500}\times100\right)\% \cr
& = 30\% \cr} $$

Question 64. Directions (1 - 5): Study the following pie-charts carefully and answer the questions that follow:

& \text{Science → } \frac{22}{100}\times3500 = 770 \cr
& \text{Commerce → } \frac{12}{100}\times3500 = 420 \cr
& \text{Management → } \frac{16}{100}\times3500 = 560 \cr} $$
Number of girls enrolled in various streams:
$$\eqalign{
& \text{IT → } \frac{18}{100}\times1500 = 270 \cr

& \text{Commerce → } \frac{21}{100}\times1500 = 315 \cr
& \text{Management → } \frac{12}{100}\times1500 = 180 \cr} $$
(Number of girls enrolled in Arts) : (Number of boys enrolled in Science)
= 570 : (770 - 165)
= 570 : 605
= 114 : 121
