Ratio of boys:girls = 9:5
Sum total of ratio = 14 parts
Total strength = 462
14====462
1 part===462/14 = 33
Boys--9 parts== 9*33 = 297 = No: of boys.
Hope it helps.

Let the common factor be x
let the number of boys and girls be 9x and 5x
Therefore A/Q
9x +5x = 462
14x = 462
x = 33
Therefore number of boys = 9×33 = 297
