KI UNIQUE QUANTITATIVE ABILITY
This section tests the mathematical skills of the examinee.
- It contains 40 questions and carries 40 marks. The time allotted for this section is 40 minutes.
- It covers various topics of algebra, arithmetic, geometry and area mensuration.
- It measures the aptitude of the examinee in quantitative terms.
- Be well equipped with different short cut methods that are applicable.
If Quantity A: 1/7 and Quantity B: 14.28%, then a person knowing fractions can easily guess that Qty A is 12.8% and is less than Qty B.This can be guessed in less than half a minute.
- About 70% of the questions are from arithmetic section in quant, so while preparing for MAT, do concentrate on arithmetic topics much more.
- Proper time allocation is the need for cracking MAT.
- MAT Test has relatively easy math sums except probability and permutations which may prove difficult. Generally the paper can be solved with some patience.
- Learn your mathematical tables up to 30, square roots and cube roots. These assist in minimizing the calculation time required. Memorise all the rules of easy solving techniques, you come across.
- Be very careful with the units used. There may be a need to do conversions to get an accurate answer, so learn these, especially if the multiple-choice answers are given in a different unit altogether.
- Improve your speed in calculation:
80% of the time is spent on cracking the concept in any question, 20% is spent on calculation. To ensure speedier calculation, everyday in the morning (for at least five days a week) one must practice calculations like addition, subtraction, multiplication, and division for about 10 minutes. This practice can save a lot of precious time in the actual exam.
EXAMPLES OF QUANT QUESTION TYPES:
Question type 1
Anita had to do a multiplication. Instead of taking 35 as one of the multipliers, she took 53. As a result, the product went up by 540. What is the new product?
Correct choice is (4) and Correct Answer is 1590
Question type 2
A piece of equipment cost a certain factory Rs. 600,000. If it depreciates in value, 15% the first year, 13.5 % the next year, 12% the third year, and so on, what will be its value at the end of 10 years, all percentages applying to the original cost?
Let the cost of equipment be Rs. 100.
Now the percentages of depreciation at the end of 1st, 2nd, 3rd years are 15, 13.5, 12, which are in A.P., with a = 15 and d = - 1.5.
Hence, percentage of depreciation in the tenth year = a + (10-1) d = 15 + 9 (-1.5) = 1.5
Also total value depreciated in 10 years = 15 + 13.5 + 12 + ... + 1.5 = 82.5
Hence, the value of equipment at the end of 10 years=100 - 82.5 = 17.5.
The total cost being Rs. 6, 00,000/100 * 17.5 = Rs. 1,05,000.
