Question
The ratio of the number of boys and girls in a school is
23:17. If 45% of the boys and 50% of the girls got passed out of 1600 students, the approximate percentage of the students who got failed is: type-sscSolution
Total no. of students = 1600 Boys = 1600 x (23/40) = 920 and Girls = 1600 x (17/40) = 680 45% of boys who got passed = 920 x (45/100) = 414 50% of girls who got passed = 680 x (50/100) = 340 Therefore no. of students who got failed = 1600 - (414+ 340) = 846 Required % = [(846/1600)] x 100 = 52.87% approx.
