[GMAT math practice question]
Four values from a data set of 5 elements are 10, 10, 11, and 11. What is the fifth data value?
1) The range of the data set is 2
2) The average of the data values is greater than 10
=>
Forget conventional ways of solving math questions. For DS problems, the VA (Variable Approach) method is the quickest and easiest way to find the answer without actually solving the problem. Remember that equal numbers of variables and independent equations ensure a solution.
