The colour and pattern of a bar denotes the ship mode (First Class \/ Second Class \/ Standard Class). The left end point of a bar indicates the booking day of the order, while the right end point indicates the dispatch day of the order. The difference between the dispatch day and the booking day (measured in terms of the number of days) is called the processing time of the order. For the same category, an order is considered for booking only after the previous order of the same category is dispatched. No two consecutive orders of the same category had identical ship mode during this period.<\/p>\n<p>For example, there were only two orders in the furnishing category during this period. The first one was shipped in the Second Class. It was booked on Sep 1 and dispatched on Sep 5. The second order was shipped in the Standard class. It was booked on Sep 5 (although the order might have been placed before that) and dispatched on Sep 12. So the processing times were 4 and 7 days respectively for these orders.<\/p>\n<p><b>Question 1:\u00a0<\/b>How many days between Sep 1 and Sep 14 (both inclusive) had no booking from this client considering all the above categories?<\/p>\n<p><b>1)\u00a0Answer:\u00a06<\/b><\/p>\n<p class=\"text-center\"><a href=\"\/25-how-many-days-between-sep-1-and-sep-14-both-inclus-x-cat-2021-slot-2?utm_source=blog&amp;utm_medium=video&amp;utm_campaign=video_solution\" target=\"_blank\" class=\"btn btn-info \">View Video Solution<\/a><\/p>\n<p><b>Solution:<\/b><\/p>\n<p>Accumulating all the data :<br \/>\nWe get the following table :<\/p>\n<p><img decoding=\"async\" class=\"img-responsive\" src=\"https:\/\/media-cdn.cracku.in\/uploads\/image_pCh9MpQ.png\" data-image=\"image.png\" \/><\/p>\n<p>Note a-b : represents the duration where a is the day when order is booked and b is the day when it is dispatched .<br \/>\nNow No booking days from the table are : September 8,9,10,11,12 and 14.<br \/>\nSo a total of 6 days .<\/p>\n<p><b>Question 2:\u00a0<\/b>What was the average processing time of all orders in the categories which had only one type of ship mode?<\/p>\n<p><b>2)\u00a0Answer:\u00a011<\/b><\/p>\n<p class=\"text-center\"><a href=\"\/26-what-was-the-average-processing-time-of-all-orders-x-cat-2021-slot-2?utm_source=blog&amp;utm_medium=video&amp;utm_campaign=video_solution\" target=\"_blank\" class=\"btn btn-info \">View Video Solution<\/a><\/p>\n<p><b>Solution:<\/b><\/p>\n<p>Accumulating all the data :<br \/>\nWe get the following table :<\/p>\n<p><img decoding=\"async\" class=\"img-responsive\" src=\"https:\/\/media-cdn.cracku.in\/uploads\/image_pCh9MpQ.png\" data-image=\"image.png\" \/><\/p>\n<p>Note a-b : represents the duration where a is the day when order is booked and b is the day when it is dispatched .<br \/>\nNow Envelopes and Accessories has only 1 ship mode i.e Standard class .<br \/>\nSo therefore processing days for envelopes = 7-3 =4<br \/>\nand processing days for accessories = 19-1 =18<br \/>\nTherefore average =\u00a0$\\frac{\\left(18+4\\right)}{2}=11$<\/p>\n<p><b>Question 3:\u00a0<\/b>The sequence of categories &#8212;
