Let the total students be = 1/1
fraction of the boys = 2/3
fraction of the girls = 1/1 - 2/3 = 1/3
total number of girls = 17
total strength of the class = 17 × 3/1 = 51
total number of boys = 51 × 2/3 = 34.
fraction of the boys = 2/3
fraction of the girls = 1/1 - 2/3 = 1/3
total number of girls = 17
total strength of the class = 17 × 3/1 = 51
total number of boys = 51 × 2/3 = 34.
