What's your shortcut ?

the original solutionhere was to assume what the maximum value the 10th student take will keeping the 1st student minimum to get the maximum mean of the group and to find the minimum mean of the group consider the lowest possible value of 10th and the highest possible value of 1st and by this, we will have both max and min mean of the group and difference of which we will get the answer.shortcuthere the difference between the 10th and 1st will be of 40 coz from 2 to 9 the minimum mean they have is 42 and the max mean is 47 so 8 elements with a difference is of 5(47-42) so the total available difference between 10th and 1st element is of 40 and this is to be divided among 10 elements to get the mean of the group so 40 divided by 10 we get 4 as an answer.

need similar Question can I get a similar question made by you sir/ma'am? Because I made a shortcut but don't have other questions to apply, so can you please send similar questions so that I can try that shortcut on these questions as well. And if possible sir/ma'am please send the solution as well so that I can cross verify myself
