| Saksham | Re: Shortcut Tricks to Solve Bank Exams Hello, I am providing here you the mathematics tricks that one may see in the bank exams as under: Squaring: In this simple trick we 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 Multiplication: Simply multiply the number by 10 and then divide it by 2. For example 99×5= 990/2= 495 Multiplication with 4 Multiplication with 9 Multiplication with 6 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 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 |
