In a class of 100 students 50 girls and 30 boys voted for AAP and the number of boys and the number of girls who voted for Congress are equal.
6. Find the ratio of number of boys to that of the number of girls.
a)1:2 b) 2:3 c) 2:1 d) 3:2

7. How many girls voted for Congress?
a) 5
b) 10
c) 15
d) 20

• Condition 1: Who voted for AAP : G-50 B-30 (T=50+30=80)
  Condition 2: Who voted for Congress (No. of boys == No. of Girls)
  20 students were left out of 100.
  Therefore (10=10)(No.of boys == No.of Girls)
  ANS::
  Total no of girls =(50+10)=60
  Total no of boys=(30+10)=40
  Ratio of boys :: girls
  40::60 == 2:3
  Girls voted for congress=10
