A newspaper vendor picks up copies of various newspapers from a center and distributes them to his customers as per their subscription. Subscription means that the customer will receive a copy of that news paper on all days throughout the month. On the last day of each month, he prepares the bill for each customer for that month and collects the payment on the 1st day of the next month. The details of various newspapers along with their retail price per copy on weekdays (Mon-Sun) are shown below. The customers are given bills according to the retail price of the copy of the newspaper they have subscribed to.
Mr. Sharma has subscribed for ET and PK only. If ₹x is the bill of Mr. Sharma for the month of April, then the bill will be
We know that in a month, the number of days can be 28,29,30 or 31.
Based on this, each newspaper's bill will be prepared for a particular month.
Mr. Sharma has subscribed for ET and PK only. If ₹x is the bill of Mr. Sharma for the month of April, then the bill will be
A) ET and PK
Cost of ET newspaper (28 days) = ₹120 (30*4)
Cost of PK newspaper (28 days) = ₹72 (18*4)
For the remaining 2 days, the days can be any two consecutive days from Monday, Tuesday,....Saturday and Sunday.
So, calculate the total price of ET and PK for each day.
Monday = 5
Tuesday = 4
Wednesday = 4
Thursday = 5
Friday = 4
Saturday = 13
Sunday = 13
So for the minimum bill for one month, we consider two consecutive days with the lowest price of both newspapers.
That is, we assume the days are Tuesday and Wednesday.
So minimum bill = 120+72+4+4 = 200
For maximum bill, we assume the two consecutive days with the maximum price of both newspapers.
That is, we assume the two extra days are Saturday and Sunday.
So maximum bill = 120+72+13+13 = 218
So, the range of x will lie $$200 \leq x \leq 218$$
