What topics are in a logical reasoning test?

Most placement and competitive exam reasoning sections cover number and letter series, coding-decoding, blood relations, direction sense, syllogisms, seating arrangement, ranking and order, analogies, odd one out, and clock and calendar questions. Bigger exams add puzzles and data sufficiency. The topics in this practice test are the ones that appear most often.

How do I solve syllogism questions quickly?

Draw each statement as circles: “All A are B” puts circle A inside circle B, “Some A are B” overlaps them, and “No A is B” keeps them apart. A conclusion follows only if it is true in every diagram you can draw from the statements. If you can draw even one diagram where it is false, it does not follow.

Is logical reasoning harder than quantitative aptitude?

It is different, not harder. Reasoning needs less formula knowledge and more careful reading, so most people improve faster in reasoning with practice. Mistakes usually come from misreading left and right or skipping a clue, not from difficult calculations.

How many questions should I practise per day?

Around 20 to 30 mixed reasoning questions a day for two to three weeks is enough for most placement tests. Time yourself, review every wrong answer, and spend extra time on the topic you get wrong most often.

How this test is scored

Each correct answer earns one mark and there is no negative marking. A score of 18 or more out of 25 is a strong result; below 12 means you should practise the weaker topics before a real test.

On the result screen, below 50% means the topics need more practice, 50–75% is a good base to build on, and above 75% means you are ready for questions like these. These bands are for your own practice only.

How to prepare

Draw it out. For direction sense, blood relations and seating, a quick sketch on rough paper prevents most mistakes.
For syllogisms, use simple circle diagrams and only accept a conclusion that is true in every possible diagram.
For series, first check the differences between terms, then look for multiplication, squares, cubes or primes.
Memorise letter positions (A=1 to Z=26) and the reverse positions (A=26 to Z=1) to speed up coding-decoding.
In seating puzzles, place the fixed clues first (ends, middle, opposite) and fill the flexible ones last.
