About this maths and data test
This is the hardest numerical test in the series. It moves from number patterns into arithmetic reasoning, fractions, ratios and percentages, everyday measurement and short data tables. Every question has a single calculated answer, shown in the review.
How to get the most from it
Write each step on paper. For percentage questions, convert to decimals. For data questions, find the numbers you need before you calculate. If an answer looks odd, check the units.
What this test practises
Maths and data questions test whether you can turn a short description into the right calculation, carry it out in steps, and decide whether the answer is sensible. The data items use small tables, so you also practise finding the correct row and column before you do any arithmetic. These skills are used in science practicals, in reading a bill or a bank statement, and in understanding the statistics you meet in the news.
A worked example
Percentages: A jacket costs Rs 2,000. It is reduced by 15%, and the sale price is then reduced by a further 10%. What is the final price?
Answer: Rs 1,530. After the first reduction the price is 2,000 × 0.85 = Rs 1,700. After the second it is 1,700 × 0.90 = Rs 1,530. The two reductions do not add up to 25% of the original price, because the second 10% is taken from a smaller amount.
Data table: A shop sold 12, 18, 15 and 21 notebooks on four days. What is the mean number sold per day?
Answer: 16.5. Add the four values to get 66, then divide by 4.
Common mistakes and how to avoid them
Adding successive percentage changes instead of applying them one after the other.
Reading the wrong column in a table, or mixing units such as centimetres and metres.
Calculating before you have worked out exactly what the question asks.
Not checking whether the answer is reasonable, for example a price that is higher than the original after a discount.
Your mark out of 100 shows how you did on these 50 questions on one day. It is not an IQ number, because a real IQ score comes from a standardised test given and interpreted by a qualified psychologist and compared with a large norm group. Use the section scores to choose what to practise, and retake the test after a week or two to see progress. Tiredness, noise and stress change results, so one low score is not a verdict on your ability.
