The average marks obtained by 6 students in a class is
60. If the topper leaves, the average drops to 55. Find the marks of the topper.Solution
Let the marks of the student who left be ‘x’. So, x + (60 – 5) × 5 = 6 × 60 x + 55 × 5 = 360 x + 275 = 360 x = 360 – 275 x = 85 So, marks of the topper were 85.
