Question
The average number of pencils distributed among five
students is 10. If each student received 1 pencil more than the one before him, then find the highest number of pencils received by any student.Solution
Let the pencils received by 1st student be ‘x’
According to the question,
(x + x + 1 + x + 2 + x + 3 + x + 4) = 10 × 5
Or, 5x + 10 = 50
Or, 5x = 40
Or, x = 8
Therefore, highest number of pencils received by any student = (x + 4) = 12
