Estimation & Number SenseRoughly right in eight seconds beats exactly right in forty — 22 questions of number sense with no calculator.
Estimation & Number Sense measures the numeracy people actually use in meetings: magnitude estimates, rate and unit conversions, close-call comparisons, fraction-percent instincts and best-offer judgements. Twenty-two items in 18 minutes, speed-weighted; a good estimate suffices and sloppy rounding does not.
Options spaced so that estimation works and carelessness does not
Roughly what is forty-nine times twenty-one? Which of four fractions sits closest to one? Which total is larger — five payments just under two hundred or four just over two hundred and fifty? A currency moves from one rate to another; roughly what percentage is that? Twenty-two items in eighteen minutes leave about fifty seconds each, which is enough to estimate and not enough to compute. The items cover magnitude, rates, unit conversions, close-call comparisons, fraction-to-percent instincts and which-offer-is-cheaper judgements — the numeracy that decides whether you challenge a figure in a meeting or let it pass.
The bank is original and follows international numeracy-fluency conventions, with every key verified by exact computation even though the candidate is expected to estimate. The option design is the point: the correct option and its neighbours are spaced so that a sensible rounding lands on the key, while rounding in the wrong direction, dropping a zero or confusing a rate with a difference lands on the adjacent trap. Every explanation shows both the exact answer and the quick estimation route that would have reached it in seconds, so the review teaches the mental shortcuts as well as the arithmetic.
The report scores Numerical Reasoning and Cognitive Speed & Agility separately, banded from Emerging to Exceptional with coaching interpretations written for people who handle numbers live — in sales calls, budget reviews, procurement negotiations and operations stand-ups. The AI-written narrative says whether you lose marks by estimating badly or by not estimating at all and running out of time. The question-by-question review covers all 22 items, and the growth plan prioritises the lower competency with the estimation habits to drill.
What you walk away with
Numerical Reasoning covers whether your estimates land in the right place; Cognitive Speed & Agility covers whether you make them fast enough to finish. Two bars tell you whether to practise the shortcuts or to trust them sooner.
Each explanation shows the exact answer and the estimation route that reaches it in seconds — round one factor up and the other down, compare to a benchmark fraction, convert the rate before the difference — so the review is a set of mental tools, not a mark sheet.
Because each trap corresponds to a specific careless move — rounding both factors the same way, dropping a zero, reading a rate as a difference — the narrative can say which one recurs, which is more useful than knowing you were roughly wrong.
Built from your lower competency, the plan sets out the estimation habits to drill and where to apply them — the budget review, the supplier quote, the conversion in a sales call — before recommending the business-arithmetic test as the exact-method complement.

- Hiring teams screening for the numerical fluency that lets a hire challenge a wrong figure on the spot
- Anyone who reaches for a calculator for arithmetic a colleague does in their head
Every wrong figure that passes in a meeting passed because nobody estimated it.

Frequently asked questions
The numeracy people actually use in meetings rather than at a desk: rough magnitude estimates, rate and unit conversions, close-call comparisons, fraction-to-percent instincts and which-offer-is-cheaper judgements. Twenty-two items in 18 minutes, deliberately too fast to compute exactly and just slow enough to estimate well. It is for professionals who handle numbers live, candidates facing a speed-numeracy round, and teams hiring for numerical fluency.
Sensible rounding is exactly what the test rewards. Every key is verified by exact computation, and the options are spaced so that a good estimate lands on the key while rounding the wrong way, dropping a zero or confusing a rate with a difference lands on the adjacent trap. Answers roll into two banded competencies, Numerical Reasoning and Cognitive Speed & Agility, and an overall 0–100 score. The bands describe your current fluency, not a cut-off.
Eighteen minutes for 22 items in one sitting, on any device. The report is generated immediately from your responses: overall banded score, radar and banded bars for the two competencies with coaching interpretations, an AI-written narrative naming your rounding habit, strengths and development areas, a prioritised growth plan and a question-by-question review showing the exact answer and the quick estimation route for every item. Everything is included; nothing further to unlock.
Hiring teams use the two bands to find candidates who can challenge a wrong figure on the spot, which matters in sales, procurement, consulting and operations, and use the shortcut explanations as interview prompts. Individuals drill the estimation habits the plan names, apply them in the next budget review, and retake to see whether the speed band moves. The business-arithmetic test is the natural exact-method complement.
Yes. Magnitude, rates, conversions and comparisons are the same arithmetic in any currency; a few items use rupee amounts and one uses a rupee-dollar rate, but each is proportional and the estimation routes apply anywhere. The formats follow international numeracy-fluency conventions and bands are descriptive rather than normed. The test is priced in INR and USD, with the live price shown on this page in your currency.
