# Wipro quantitative aptitude questions

Quantitative ability is the crux of the Wipro aptitude exam. It's really important to score well in this section. When we analyzed the previous year's papers we found that the major focus is on profit loss, number system, ratio proportion, and percentages.

If you have sufficient time before the exam, then its definitely recommended solving as many questions as possible. The reason is to improve accuracy and speed so that you can complete quant fast and then move to reasoning and allot more time to it as the questions are sometimes unpredictable and lengthy.

Once you are done preparing for this section move to verbal ability, logical reasoning, and coding and later solve at least 2 practice papers i.e. wipro placement paper 1 and wipro placement paper 2
