Number of children in a school = 260
Percentage of girls in the school = 55%
Number of girls in the school = (55/100) 260
                                                = 14300/100
                                                 = 143
So there were 143 girls in the school among 260 children
Percentage of children going for the school trip = 10%
Then
Number of students going for the school trip = (10/100) 260
                                                                        = 26
So 26 children are going for the school trip. I hope the procedure is clear enough for you to face similar problems in future.
