100
The first 10 multiples of 95: 95, 190, 285, 380, 475, 570, 665, 760, 855, 950
The multiples of 10 between 100 and 200 are 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, and 200
There are 13 : 105, 112, 119, 126, 133, 140, 147, 154, 161, 168, 175, 182, 189.
Multiples of 19 include: 19, 38, 57, 76, 95, 114, 133, 152, 171, 190, 209, 228, 247, 266, 285, 304, 323, 342, 361, 380, etc... you must add 19 each time.19, 38, 57, 76, 95, 114, 133, 152, 171, 190, 209, 228, ...(The first 12 are given above, I'll leave the remaining infinite number of them for you to do.)38 57 76 95 114 133 152 171 190 and so on ...
203.3= 190 + (7%/100% * 190)= 190 + (7/100 * 190)= 190 + (0.07 * 190)= 190 + (13.3)= 203.3
The mean is the sum of all of the numbers in the series divided by the number of items in the series. In this case it is the SUM(10...190), which equals 1900. There are 19 items in the series, so the mean is 1900/19 = 100.
Take the numbers in pairs. avg(10, 190) = 100 avg(20, 180) = 100 . . . avg(90, 110) = 100 It is easy to see the overall average is 100.
