Am not sure
- draw 2 disjointed circles for the boys and girls,
- draw a circle intersecting both of those two circles, the two separate overlaps would be boys playing sports and girls playing sports.
We are told that 101 girls do not sport, so fill that in
We are told that there are 350 girls, so 249 girls play sports
Fill in that part.
We are told that 559 students play sports, and we know 249 of those are girls, so 310 boys play sports. Fill in that part of the Venn diagram.
That leaves us with "boys not playing sports" as the only missing part.
But there were 750 students, so
number of boys not playing sports = 750 - (101+249+310) = 90
