Forget conventional ways of solving math questions. In DS, VA (Variable Approach) method is the easiest and quickest way to find the answer without actually solving the problem. Remember that equal number of variables and independent equations ensures a solution.
We can assume that a1 ≤ a2 ≤ a3 ≤ a4 ≤a5. The question asks what the value of a3 is.
In the original condition, there is 5 variables and 0 equation. Therefore, E is most likely to be the answer.
Condition 1)
a1 = 10, a2
