Question
The average number of balloons distributed among five
kids is 9. If each kid received 1 balloon more than the kid before, then find the highest number of balloons received by any kid.Solution
Let the balloons received by 1st kid be ‘x’
According to the question,
(x + x + 1 + x + 2 + x + 3 + x + 4) = 9 × 5
Or, 5x + 10 = 45
Or, 5x = 35
Or, x = 7
Therefore, highest number of balloons received by any kid = (x + 4) = 11
