The mean of the $5$smallest numbers from a group is $15$ while the mean of all the $13$numbers of the group taken together is $17$. What is the mean of the$8$largest numbers?

A and B together can do a piece of work in $10$ days. If A can do the work in $15$ days, find in how many days that B alone can do the same work. Given below are the steps involved in solving the above problem. Arrange them in sequential order.

(A) One day's work of B is  $\frac{1}{10}-\frac{1}{15}$

(B) One day's work of A and B is $\frac{1}{10}$ and one day's work of A is $\frac{1}{15}$

(C) B alone can do the work in $30$ days

(D) One day's work of B is $\frac{1}{30}$
