 Given 999 distinct numbers between 1 and 1000, find one/two that is/are missing.4 Answersone is missing: there are plenty of ways of doing this, simplest is to sum all numbers, subtract from 1+2+...+1000. two are missing: you'd need 2 equations, a+b = something, and a*b = something_else. first equation can be generated using the technique mentioned above, try summing the squares of numbers for the next equation.missign number = Sum to 1000 - Sum of all given numbers.Its 1 and 1000, cuz the question say between 1 to 1000, i.e., now only 1 and 1000 are leftShow More Responses1 number missing: Calculate sum of numbers 1 - 1000 , which is (1000)(1001) / 2, and then subtract actual sum from that. You'll get your missing number. 2 numbers missing: Calculate sum of numbers AND sum of squares of numbers (n)(n + 1)(2n + 1) / 6, subtract from actual sum. You have two equations, two variables, solve. You can continue this pattern for n numbers, pretty sure.

 "Why are sewer caps round?"3 AnswersAs long as you can answer their questions adequately, you'll be fine. I answered the sewer cap question with "the caps are heavy and any other shape would be hard to roll away when access is needed to the sewer. Also, a shape with corners could warp and potentially damage tires", etc.A sewer cap is round because it is the only shape that, when removing the cap, cannot fall into the hole.This is not always the case.In China the sewer cap could be either round and square.But square one comes in small size.
