Ans: Hello Student, Please find answer to your question below
[x] is the greatest integer that is less than or equal to x.
[x] is 0 if x lies between 0 (included) and 1 (excluded) [x] is 1 if x lies between 1 (included) and 2 (excluded)
In this case, the xthterm is where x varies from 0 to 99 (both included) This will be equal to zero till the value inside is atleast 1. Note that the last term is [3/4 + 99/100] = [1.74] = 1. So every term will equal 1, starting from the term where 3/4+ x/100 = 1 Thus from x = 25, to x = 99, each term evaluates to 1. And from x = 0 to x = 24, each term equal to zero. So, the sum will be equal to: how many numbers are between 25 and 99 (both included) = 99 – 25 + 1 = 75
