Union Bank LBO sets 35 Quantitative Aptitude questions for 60 marks in the Online Examination, 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.

Permutations and combinations · solved example
In how many ways can 2 people be chosen from a group of 5?
Solution
This is 5C2 = 5!/(2!×3!) = 10.
Simplification · solved example
What value should come in place of the question mark? 18 x 24 / 6 + 15% of 480 = ?
Solution
Division and multiplication bind tighter than addition, so resolve the first term on its own: 18 x 24 = 432, and 432 / 6 = 72. For the second term, 15% is a tenth plus half a tenth, so 48 + 24 = 72. The total is 144. Reading left to right and dividing 432 by 6 only after adding would give a different answer, which is what the ordering of this expression is testing.
Simple interest · solved example
Find the simple interest on Rs 2500 at 12% per annum for 2 years.
Solution
SI = P×R×T/100 = 2500×12×2/100 = 600.
