Answer» Let the maximum marks be 'x'.Then, according to the question.(25 % of x) + 30 = (50 % of x) - 20⇒ x/4 + 30 = x/2 - 20⇒ (x/4) - (x/2) = - 20 - 30⇒ (x - 2x)/4 = - 50⇒ - x/4 = - 50⇒ - x = - 200⇒ x = 200So, the maximum marks are 200. Minimum passing marks are = x/4 + 30= 200/4 + 30= 50 + 30= 80 marks Minimum passing marks are 80. |
