Question
In a test, P got 26% of total marks and failed by 30
marks while Q got 46% of total marks which is 24 more than passing marks. Find the total marks of the test.Solution
Let the total marks of the test be ‘x’ Therefore, marks scored by P = 0.26x Therefore, passing marks of the test = 0.26x + 30 Marks scored by Q = 0.46x Also, passing marks of the test = 0.46x – 24 Therefore, 0.26x + 30 = 0.46x – 24 Or, 0.26x = 54 Or, x = 54/0.2 = 270 Therefore, total marks of the test = 270
