Method of solving this CAT Question from Ratio, Mixtures and Averages: How the individual data points affect the average?

Total number of chocolates = 13 * 17 = 221
For one box to have maximum number of chocolates, the other boxes need to have minimum number of chocolates i.e. 11, 12, ………………….., 22
Total = 11 * 12 + (0+1+2+……………+11)
= 132 + 66 = 198
Therefore, maximum possible chocolates = 221 – 198 = 23

The question is "what can be the maximum possible number of chocolates in any box?"

Choice A is the correct answer.
