Oh, dude, math time! So, if you add up all those numbers, you get 209. It's like, basic addition, you know? Just throw those numbers together and boom, you've got the answer. Math can be fun... sometimes.

31
I'll assume you mean the first 30 positive integers, and not real numbers. That would be 31 X 15, or 465. 30 + 1 = 31, 29 + 2 = 31, 28 + 3 = 31, etc. This can happen 15 times, with 15 + 16 = 31 being the fifteenth.
The answer is 203. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
1+12=13+15=28+2=30+29=59.
The median of 31 28 30 31 30 is 30.
Put them in order as 28 30 30 31 31 and the median is the number in the middle, which is 30.
228
1 plus 30 is 31
30
31 28 31 31 30 31 30 31 30 31 30 31
Median is the middle number of a list that ascends or descends in order. 30 would be the median of 28, 30, 30, 31, 31.

1000 + 30 + 74 + 31 = 1135
Totally there is 365 days per year. But Months have 30 and 31 days in them. so for example if 73 days worked then its is 31 plus 28 plus 14 days. we have to write 31 Jan. plus 28 Feb. plus 31 Mar plus etc. and see which span of addition your number comes. In example 73 equals 31 plus 28 plus 14 so it is 2 months and 14 days worked per year.
