Quantitative Aptitude appears in the Odisha Police Sepoy/Constable syllabus below. The official pattern does not break it into its own timed section, so treat the whole topic list as fair game.
Speed decides this section. The arithmetic and data-interpretation sets are where the marks are, so the priority is a reliable method and quick calculation rather than exotic shortcuts. Lock down tables, squares and reciprocals, then drill data interpretation until reading the set is faster than solving it.
Every topic in the official syllabus. The linked ones open a set of solved questions you can practise straight away.
Written to the Odisha Police Sepoy/Constable pattern, with the answer key and the method behind it — a look at how the section is actually set before you drill the full topic sets.

Average · solved example
The average of five numbers is 18. If four of them are 15, 16, 20 and 21, find the fifth number.
Solution
Sum of five numbers = 18 × 5 = 90. Sum of the four given numbers = 15 + 16 + 20 + 21 = 72. The fifth number = 90 − 72 = 18.
Profit and loss · solved example
An item bought for Rs 400 is sold for Rs 460. What is the profit percentage?
Solution
Profit = 460 − 400 = Rs 60. Profit % = (60/400) × 100 = 15%. The percentage is always on cost price unless the question states otherwise.
Time and work · solved example
A can finish a task in 10 days and B in 15 days. Working together, in how many days will they finish it?
Solution
A's one-day work = 1/10, B's = 1/15. Combined daily work = 1/10 + 1/15 = (3 + 2)/30 = 5/30 = 1/6. So they finish together in 6 days.
