Numerical Ability gives you 25 questions in 35 minutes — under 90 seconds per question on classic arithmetic. Every topic below appears in memory-based Cognizant papers drive after drive.
Most-tested aptitude topics
- Speed–Time–Distance — trains overtaking cyclists/runners (relative speed)
- Time & Work — “assisted on every third day” formats
- Percentages and successive price changes
- Compound Interest — year-on-year amount differences
- Ages with future ratios
- Remainders and number-system tricks
- Permutations & Combinations (committee selection)
- Weighted averages with percentage chains

A 200-meter long train is traveling at 72 km/hr. It overtakes a cyclist moving in the same direction at 18 km/hr. How long does it take for the train to pass the cyclist completely?
Raju, Ramu and Razi can do a piece of work in 20, 30 and 60 days respectively. If Raju is assisted by Ramu and Razi on every third day, then in how many days will Raju complete the work?
A committee of 5 people is to be formed from a group of 7 doctors and 6 engineers. In how many ways can the committee be formed if it must contain at least 3 doctors?
Tip: for train questions, convert km/hr to m/s by multiplying by 5/18 before anything else — nearly every Cognizant speed question hinges on that one conversion.
