50 + 30 + 10 = 90% where is other 10%
It is mentioned there only science and only maths. Then where is the value of students who have tuition in both?

I hope the left 10% studies both Maths and Science
Total students = 15000
Tuition students = 15000 x 40/100 = 6000
Students studying both math and science = 6000 x 10/100 = 600
