  Remaining 40 are girls.

• Total students: 50
  10 boys got 85%
  so remaining student:50-10=40
  1/5 total remaining student got 85%=40*1/5=8
  i.e.remains:40-8=32 girls
  ans:32

• guys reads que correctly....the que ask "how many grls got more than 85% marks in mathematics".....
  so ANS: B
  bcz...
  from statement A -- shows that there are only 10 boys who got more than 85%...
  and in statement B -- say that 1/5 of 50 =10 student ..and in statement A it already says that there r 10 boys who got more than 85%....which means no girl got more than 85%.......so ans B satisfied.
