Its approach showdown time, guys!

e-GMAT invites you to hone your quants skill in Integrated Reasoning. We welcome you to post your response to question # 3 of exercise question given in compare-mean-and-median-in-less-than-20-seconds-146191.html article. (The dataset is given at the bottom of article).

Question # 3 is given here for your ready reference- If 2 new students Manish and Imran are included; whose Lawn Tennis scores are 5 & 19 respectively, then the mean score of Lawn Tennis increases by at least 2 points.

The Reward

The best approach judged by e-GMAT experts will be recognized, and awarded. The reward would be ‘Free subscription to e-GMAT IR course’ for 6 months.

Criterion of Best Approach

The best approach would be judged laying suitable weights on 3 listed parameters.

1. Efficient – Simply put, the answer to the question # 3 can be answered in least possible time.
2. Concepts – The approach should be articulated well, and lucid to be understand by an above average GMAT test taker. It should not use higher mathematical concepts, that are out of GMAT quants concept scope.
3. Less calculation intensive – Given that in IR section, you have an access to calculator, but less calculation is always good. However, if your approach scores on efficiency with an application of some calculation, you are welcome!

Enjoy the challenge!
