If 20% of number of girls from school P and 40% of number of boys from same school are selected for a science project, what is sum of number of boys and girls who are not selected for science project?

Explanation

20% of number of girls from school P are selected for a science project = 20% of 180 = 36 40% of number of boys from school P are selected for a science project = 40% of (240 -180) = 24 Sum of number of boys and girls who are not selected for science project = 240 -(36 + 24) = 180
