Let the number of boys be X
therefore,
the number of girls = 66/7 % × X
the number of girls = 66/700 × X
Total no. of students = Number of (boys + girls)
1101 = X + 66X/700
1101 = (700X + 66X)/700
1101 × 700 = 766X
X = 1007
Number of boys = 1007
Number of girls = 94
therefore,
the number of girls = 66/7 % × X
the number of girls = 66/700 × X
Total no. of students = Number of (boys + girls)
1101 = X + 66X/700
1101 = (700X + 66X)/700
1101 × 700 = 766X
X = 1007
Number of boys = 1007
Number of girls = 94
