Explanation:

From school D: swimming + painting = 100 – 40 = 60%
percentage point of students who took part in swimming is 10% greater than that of students who took part in painting from school D.
So swimming = 35%, and painting = 25%
Boys from school B = 280 which is 6 2/3% = 20/3% less than boys from school D
So (x – 280)/x * 100 = 20/3
Solve, x = 300 = boys from D
Girls from school D = 280, so total students = 300+280 = 580
So number of students who did not take part in swimming = (40+25)% of 580 = 377
