Question
Simran scored 25% marks in a test and failed by 50
marks, whereas Neil scored 40% marks in the same test and failed by 20 marks. Find the passing marks of the test.Solution
ATQ, Let the maximum marks be 100m Marks scored by Simran = 25% of 100m = 0.25×100m=25m. So, Passing marks = 25m+50 ------------- (I) Marks scored by Neil = 40% of 100m = 0.4×100m=40m. So, Passing marks = 40m+20 -------------- (II) Comparing equation (I) and (II): 25m+50=40m+20 40m−25m=50−20 15m=30 m=2 Put the value of m=2 in equation (I), Passing marks=(25×2)+50=100
