Answers :
1) Answer: B
Total number of students who like Physics = 30/100*500= 150
Ratio between the number of boys and girls = 2:3
Number of boys = 2/5*150= 60
2) Answer: B
Number of students who like social= 15/100*500 = 75
Number of students who like English and chemistry together = 30/100*500= 150
Hence required percentage = 75/150*100= 50%
3) Answer: A
Number of students in class X = 500
Number of students in class XII = 150%(500)= 150/100*500= 750
Number of boys = 7/15*750 =350
4) Answer: B
Total 100% = 360
Physics = 30%
hence required angle = 30/100*360= 108
5) Answer: B
Required average = (25+15+22+30)/4
= 92/4
= 23%
= 23/100*500
= 23*5
=115
