I think the answer is C. Here's how: Since M has the greatest annual salary, the differences can be setup so that: (M-J) = 2*(M-K) Simplifying, you will get: (2K - M) = J Stmt I alone, or Stmt II alone will not give you all 3 annual salaries so you can compute mean. But both together, give you K and...

This problem was pretty challenging... I think I found a way to solve it, but probably not something I would have been able to solve in 2 mins had I seen it for the first time! Here's how I approached it: 1 * 11 = 11 2 * 11 = 22 ... 10*11 = 110 ... 100*11 = 1100 101*11 = 1111 102*11 = 1122 ... 401*1...

A restaurant uses the same volume of chili paste weekly, which comes in either 15 or 25 oz cans. If the restaurant orders 40 more small cans than larger cans to fulfill it's weekly need, how many small cans does it order? The problem seems to be worded in a confusing manner. Do the combined cans me...

I saw this question on a forum for the IIM CAT prep and seemed interesting. Q: If a is an integer, and the tens digit of a^2 is 7, what is the units digit? Ans: 6 So the way I solved this was brute force by squaring numbers till I got 24-square = 576, hence assumed the rule applied to all subsequent...

Anyone / Instructors? Is there an easy way to do this using algebra? What am I missing? and If a is a positive integer, is the tens digit of a^2 odd? I. the units digit of a is equal to 4 or 6 II. the units digit of a is equal to 3 or 5 What would be the best way to approach this and solve quickly, ...
