Re: Mathematical problems solve Short tricks

As you want to get Mathematical problems solving Short tricks, so here I am providing the following Short tricks:

Mathematical Problems Solving Short Tricks

Trick 1:Quick Square
Step1: If you need to square a 2 digit number ending in 5, you can do so very easily with this trick.
Step2: Mulitply the first digit by itself + 1, and put 25 on the end.
Step3:That is all!
Step4: Ex:25 ie(2*(2+1))&25

Trick 2: Multiply by 5
Step1: Take any number, then divide it by 2
Step2:If the result is whole, add a 0 at the end.
Step3: If it is not, ignore the remainder and add a 5 at the end.
Step4: 2682 x 5 = (2682 / 2) & 5 or 0
Step5:2682 / 2 = 1341 (whole number so add 0)
Step6:Ans:13410
Step7:Let’s try another:5887 x 5,2943.5 (fractional numbers (ignore remainder, add 5)

Trick 3: Tough Multiplication
Step1: If you have a large number to multiply and one of the numbers is even, you can easily subdivide to get to the answer
Step2:Ex:32 x 125, is the same as: 16 x 250 is the same as: 8 x 500 is the same as: 4 x 1000 = 4,000

Trick 4: Subtracting from 1,000
Step1:To subtract a large number from 1,000 you can use this basic rule: subtract all but the last number from 9, then subtract the last number from 10:
Step2:Ex:1000-648
Step3: subtract 6 from 9 = 3
Step4: subtract 4 from 9 = 5
step5: subtract 8 from 10 = 2

Re: Mathematical problems solve Short tricks

Here I am attaching an attachment which will give you short tricks for solving the mathematical problems in bank exam

Syllabus of maths in Bank Exam:
Numerical problems (missing no.,series completion etc)
Percentages (like profit & loss %, marks,shares etc.,)
Market price,Cash price & Expenditure problems.
Time & Work, Speed & Distance problems
Fraction, Ratios, Average & Volume
Factoring (LCM, HCF..)
Mensuration formulas (asking you to calculate length, breadth or height of square,rectangle cube etc)
Simple interest & Compound interest (find missing variable or direct question)
Tips for preparation for mathematical section in bank exam:

Know about BODMAS (Brackets, Order, Divide, Multiply, Add, Subtract) & workout problems implementing the rule.
Use common sense to solve questions that are real life oriented (like distance, age, time)
Calculators are not permitted inside the exam hall.Hence learn shortcut methods or formulas to solve a question quickly.
Time management is essential while attending mathematical problems.So tryout some mock tests with the same number of questions while preparing.
Practice as many model papers & previous year question papers with a clock - because time management is essential for mathematical problems.
