Re: Shortcuts for Bank PO Maths Exam
In every competitive exam you have to solve aptitude question accurately in limited time so for that you must solve question directly using short tricks. List of short tricks for Maths 1. Squaring In this you need to modify the equation and make the units digit zero. After all it is easy to multiply when units digit is zero. For example - Find square of 43 = (43+3) × (43-3) + (3×3) =(46×40) + 9 = (460×4) + 9 = 1840 + 9 = 1849 2. Multiplication with 5 Simply multiply the number by 10 and then divide it by 2. For example 99×5= 990/2= 495 Multiplication with 99 Multiply the number with 100 and then minus same number from the result. Multiply 32×99 = 3200 - 32 = 3168 3. Mixture Questions related to mixtures can be easily solved by allegation method. By using allegation you can wide arrange of maths questions. Example Price of wine of $60 per liter. If Samuel is adding water with and selling the mixture for $40 per liter. Profit margin remains same. What is the ratio of water and wine in the mixture. 4. Square root Best method to find square root of large numbers is by dividing the number into parts. Let's take an example Find square √ 1936 √ 1936 = √ 4 × √ 484 = √ 4 × √ 4 × √ 121 = 2×2×11 = 44 5. Time and Work Every question in time and work chapter can be solved easily by finding efficiency of workers or subject (such as pipes). For example - A takes 10 days to complete a job. B takes 20 days to complete the same job. In how many days they will complete the job if they work together? A's efficiency = 100/10 = 10% per day B's efficiency = 100/20 = 5% per days A and B can do 15% of the work in a day if they work together. So they can do the whole job in 100/15 = 6.66 days or 6 days and 18 hours. 6. Profit and Loss In case of profit 25% of Cost Price (1/4 of CP) = 20% of Selling Price (1/5 of SP) Similarly 1/3 of CP = 1/2 of SP In case of loss 25% of Selling Price (1/4 of SP) = 20% of Cost Price (1/5 of CP) Similarly 1/3 of SP = 1/2 of CP 7. Estimation That's the most important technique. This is not a secret that every successful candidate is using this technique during exams. Example - 112 × 92 Simply 112 × 9 = 1008 Add a zero 10080 and then add 224 to 10080. Answer is 10304 Best Books on Quantitative Aptitude : QUANTITATIVE APTITUDE 17th Edition (Paperback) by S.
