All of the numbers appear once and as a mode is the most commonly occurring number, there is no mode.
To find mode first order your numbers from largest to smallest. 75, 62, 59, 49, 47. Now remove the biggest & smallest, and repeat until you have one number left. 75, 62, 59, 49, 47. 75, 62, 59, 49, 47. We're left with 59. So the mode of M{75,62,59,49,47} = 59.
53 and 22..
75% of 49= 75% * 49= 0.75 * 49= 36.75
100 x 53/75 = 70.66... %
-22
49 + 75 = 124
Method 1: 75 - 31 = 44, half of 44 is 22 which is the smaller number so the larger is 53. Method 2: 75 = 38 + 37, difference 1. Add 15 to 38 and subtract 15 from 37 and you get 53 and 22. The choice is yours...
53
-49 minus 75 is -124
49/75 x 100 = 65%
