Solve as many questions as possible on Data Sufficiency in Logical Reasoning. This way you will get the hang of the answer methodology. Solve last year’s test papers, you might be lucky to get questions on similar lines.

Check out our sample question:

Question: In which year was Rahul born?

Statements:

I   Rahul at present is 25 years younger to his mother.

II  Rahul’s Brother, born in 1964, is 35 years younger to his mother.

  1. I alone is sufficient while II alone is not sufficient.
  2. II alone is sufficient while I alone is not sufficient.
  3. Either I or II is sufficient.
  4. Neither I nor II is sufficient
  5. Both I and II are sufficient.

Such questions in Logical Reasoning require very less calculation and more of standard problem solving. The question along with the statements requires you to analyze or evaluate rather than directly calculate the solution.

Question: What will be the total weight of 10 canes, each of the same weight?

Statements:

I    One – fourth of the weight of each cane is 5 kg.

II   The total weight of three canes is 20 kilograms more than the total weight of two canes.

  1. I alone is sufficient while II alone is not sufficient.
  2. II alone is sufficient while I alone is not sufficient.
  3. Either I or II is sufficient.
  4. Neither I nor II is sufficient.
  5. Both I and II are sufficient.

Answer with Explanation:

Answer: Option C

Explanation:

From I, we can conclude that weight of each Cane = (4×5)kg = 20kg

So , total weight of 10 canes = (20×10)kg = 200kg

From II, we can conclude that

Weight of each cane = (weight of 3 canes) – (weight of 2 canes) = 20kg

So, total weight of 10 canes = (20×10)kg = 200kg
