Questions in the analytical reasoning section test your ability to analyze the situation, reason the cause/ effect and then find a solution. While questions in most of the competitive exams have options with them, but sometimes, we are not presented with options. A lot of effort is required to identify and reach the right option. What works best in such Analytical Reasoning questions is what we call as a trial and error strategy.

Try something (Guess), if it does not work, guess again. Over time, our guesses become more educated - and we tend to require fewer trials to reach our solutions.

- First of all you need to read the directions of a particular Data Sufficiency question very carefully as examiner can change the directions and even after solving all the questions correctly you mark the wrong answers.
- You need to remember the steps involved in solving a particular Data Sufficiency question and follow them in this particular order: Check A (i.e. the first statement), then Check B (i.e. the second statement) and lastly, if required, combine the two statements to get the answer.
**Do not make any assumptions**while solving Data Sufficiency questions.

The average number of people in a house is 44/8 is roughly 4.5. So what numbers should we take? 2, 3, 4, 5, 6, 7, 8, 9. Now, we should also have an average close to 5 for each set.**Let's start:**

**Analytical Reasoning - Trial and Error Strategy: Key Learning**

- Set 1: 3, 5, 7
- Set 3: 2, 4, 9
- Now, the other two sets will have an overlap. So let's guess the overlaps:
- Set 2: Overlaps are 2 and 7. So the third number will be 6. That's great! Because we have not used 6 yet.
- Set 4: Overlaps are 3 and 9. Then the third number ends up to 3 again. Wrong guess! So we need to try again. Overlaps are 3 and 4. In this case third number works out to be 8, which we have not used. Wonderful!
**So here is the answer**

- Note that this is not the only solution. There are others possibilities as well.

Mrs. Choy spent exactly Rs. 10 on 100 eggs for her shop. Large eggs cost her 50 p each. Medium eggs cost her 10 p each. Small eggs cost her 5 p each. For two of the sizes, she bought the same number of eggs. How many of each size did she buy?

Even before guessing the answer, it is important to carefully understand the statement and then narrow down to a set of numbers/ options. These options/ numbers will form a base for using the trial and error strategy.
