Question
Find the ratio of number of surgical mask to the number
of N95 masks sold on Tuesday. Answer the following questions based on the information given below: A shopkeeper sold two types of masks i.e. surgical and N95. Number of surgical masks sold on Monday is [P] which is 60 more than the number of N95 masks sold on same day. Number of surgical masks sold on Tuesday is [Q] which is 20% less than that on Monday and number of N95 masks sold on Tuesday is [R]. Total masks sold on Tuesday is 28% less than that on Monday while total masks sold on Tuesday is 432. Number of N95 masks sold on Wednesday is [S] which is 15% more than number of surgical masks sold on same day. Ratio of total masks sold on Monday to Wednesday is 60:43.Solution
Total number of masks sold on Monday = 432/0.72 = 600 Number of N95 masks sold on Monday = (600 – 60)/2 = 270 Number of surgical masks sold on Monday [P] = (600 – 270) = 330 Total number of masks sold on Tuesday = 432 Number of surgical masks sold on Tuesday [Q] = (80/100) × 330 = 264 Number of N95 masks sold on Tuesday [R] = 432 – 264 = 168 Total number of masks sold on Wednesday = (600/60) × 43 = 430 Number of surgical masks sold on Wednesday = (20/43) × 43 = 200 Number of N95 masks sold on Wednesday [S] = 430 - 200 = 230 
Required ratio = 264 : 168 = 11:7
