For a set S = {5,5,5,5,5}, removal of the median does nothing to the value of the mode. It remains equal to the median. However for a se...

You're right about the first question, but not about the second. Statement 1 only tells you the final balance if the increase was 12%. We have no idea what the actual increase was, so the first Statement is nowhere close to being sufficient - the increase may have been 1%, or it may have been 5000%...

From the question statement. C:M = 3:2 From statement 1 M:A = 7:13 = 14:26 So C:M:A = 21:14:26 There will be 14x mexicans where x>=1. So the number of americans will vary depending on the value of x. So insufficient. From statement 2 There are less than 30 mexicans. Not sufficient. Doesn't help me f...

The key to this question is to choose a number that you can use to denote the total amount of work. I'm going with 18 since that is the highest number that in the answers and is divisible by 6,2,and 3 So there are 18 total units of work Tom can finish 18 units in 6 hrs.. So he works at a rate of 3 u...
