Total students = 420
Boys = 312, Girls = 108

Total playing soccer = 250
86%of 250 = 215 are boys who play soccer.
Girls who play soccer = 35.

Total girls who do not play soccer = 108 - 35 = 73.

Correct option: B

Total students = 420
boys = 312
girls = 420-312=108
total students who play soccer = 250
boys who play soccer = 0.86*250=215
girls who play soccer= 250-215=35
girls who do not = 108-35=73
