      If the ratio of boys who passed to failed is 5:1 and for girls it is 3:2, find the total number of students who cleared the exam.

      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ,

      Number of boys = (2/3) Γ— 720 = 480

      Number of girls = (1/3) Γ— 720 = 240

      Required number of students = (5/6) Γ— 480 + (3/5) Γ— 240 = 400 + 144 = 544
