Let the total number of scholars in the school be x. Number of infants under 7 = (25 x)/100= x/4 ∴ Remaining scholars = x- x/4 = (3 x)/4 ∵ Number of girls above 7 = 4/5 of Number of boys above 7 Now, 120 = 4/5× number of boys above 7 Number of boy above 7 = 150 ∴ 3x/4 = 120 + 150 ⇒ (3 x)/4 = 270 ⟺ x = 360
