PNB LBO sets 50 Quantitative Aptitude questions for 50 marks across 2 stages, so it is worth planning your preparation around the topics below.
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.

Written to the PNB LBO 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.
Quadratic equations · solved example
In each question two equations are given. Solve them and choose the relation between x and y. I. x^2 - 7x + 12 = 0 II. y^2 - 9y + 20 = 0
Solution
The first equation factors as (x - 3)(x - 4) = 0, so x is 3 or 4. The second factors as (y - 4)(y - 5) = 0, so y is 4 or 5. Comparing every pair, x is never greater than y and can equal it (4 = 4), so x <= y.
Partnership · solved example
A invests Rs 5000 for 6 months and B invests Rs 9000 for 12 months. If the total profit is Rs 460, find A's share.
Solution
Capital×time is 30000 for A and 108000 for B. A's share = 460 × 30000/138000 = 100.
Percentage · solved example
Find 12.5% of 400.
Solution
12.5% means 12.5/100, so 12.5% of 400 = 50.
Addition · solved example
Find the sum of the consecutive numbers from 17 to 22.
Solution
The 6 numbers average 19.5, so the sum is 117.
