Rating of the Item
Logic
Level
3
If a customer has given a rating of "5" to an item he purchased, then how many more should give their own ratings in order to keep the overall/average rating of "1" to the same item?
Average rating = \(\frac{R}{C}\) where R = Sum of all ratings & C = Number of customers
NOTE: Following are the conditions to be considered i) Each customer is allowed to give only 1 rating ii) The ratings should only be given among 1 or 2 or 3 or 4 or 5 iii) No decimal values are allowed
