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

Number of votes for AAP is 80(50B+30G).
Remaining 20 Students voted for Congress.
No of girls and no of boys voted for congress are equal. So, In remaining 20 students 10 are boys and 10 are girls.
