81 - 50 = 31
50 - 19 = 31
50 subtracted by 34 = 16
39 is a composite number whose proper factors add up to 16.
It is: 23+29+31+37+41+43+47 = 251
3.020 as a mixed number is 31/50
Should be 50! Every odd integer is 1 less than the corresponding even integer and there are 50 of each in 100...

-50
It is 496.496 = 24*31 so its proper factors are 2, 4, 8, 16, 31, 62, 124 and 248. Their sum is 495.
39 is a composite number whose proper factors add up to 16.
It is: 23+29+31+37+41+43+47 = 251
There are no 5 odd numbers whose sum is 50. (The sum of 5 odd numbers is an odd number whereas 50 is an even number.)
