Study the following information to answer the given questions.

Percentage of students in various courses (A, B, C, D, E, F) and Percentage of girls out of these.

Total students : 1200
(800 girls + 400 boys)

Percentage in various courses

Total girls : 800

Percentage of Girls in Courses

1. For course D what is the respective ratio of boys and girls ?
Solution :
For course D

Number of girls = 30% of 800

= (30 x 800) / 100 = 240

Number of students

= 35 x (1/100) x 1200 = 420

So, number of boys = 420-240 = 180

So, required ratio = 180 : 240 = 3:4

2. For which pair of courses is the number of boys the same ?
Solution :
Number of boys

in course E = 12 % of 1200 - 14 % of 800

= 144 - 112  = 32

in course F = 13% of 1200 - 14% of 800 = 156 - 112 = 44

in course A = 20% of 1200 - 30% of 800 = 240 - 240 = 0

in course D = 35% of 1200 - 30% of 800 = 420 - 240 = 180

in course C = 5% of 1200 - 2% of 800 = 60-16 = 44

Obviously pair C and F is our answer

3. For course E, the number of girls is how much per cent more than the boys for course E ?
Solution :
For course E,

Number of girls = 14% of 800 = 112

Number of boys = 32

So, required percentage = (80/32) x 100 = 250

4. For which course is the number of boys the minimum ?
Solution :
From the solution 2, we can directly say that the answer is Course A.

5. How many girls are in course C ?
Solution :
Number of girls in course C
= 2% of 800 = 16

1. Hi admin ! For question no 3.. It would be like 112/32*100.. Isn't it??
