While taking a viva in class, the teacher decides to take the viva of two roll numbers at a time. For this she calls out the roll numbers from the list of roll numbers as: One roll number from the first nth roll number and Second roll number from the nth last roll number. For example if the numbers are: rollnum=[21, 24, 45, 6, 7, 23, 9, 11, 15, 18], and n=4, then :One roll number called for viva is 6 and second roll number called for viva is 9.
You need to write a python function which take a list A and nth roll number as input and return first nth roll number and Second roll number from the nth last roll number as shown in example. If nth roll number is not lies in the range of list, then function will return "n is not in range" in place of first roll number and empty string (“”) in place of second roll number.

aldo's shoes bought a shipment of 667 pairs of women's shoes for $36.00 per pair. The store sold 122 pairs at the regular selling price of $228.00 per pair, 78 pairs at a clearance sale at a discount of 35% and the remaining pairs during an inventory sale at a price that equals cost plus overhead. The store's overhead is 25% of cost.
(a) What was the price at which the shoes were sold during the clearance sale?
(b) What was the selling price during the inventory sale?
(c) What was the total profit realized on the shipment?
(d) What was the average rate of markup based on cost that was realized on the shipment?
