Math Basic Short Cut Tricks Addition, Multiplication and Division Problems and Solutions:
The Addition, Multiplication and Division are the most important part of Math Aptitude. The Questions on Addition, Multiplication and Division are commonly asked questions in any competitive exam. Here we are discussing on the Basic Math Short Tricks. Basic Math Question is asked in almost all the exams like SSC, RPSC, BANK, SBI, IBPS, Teacher, TET and Many other entrance exams.
Addition: We know that the time is the most important part of any exam. You want to crack any exam then you should go for time management. If you managed time according to the time required than everything will be easier for you. So to any kind of question you should have to know the short tricks of addition. The addition can be said the combination of two or more numbers to find total or sum of those numbers. Like 5+4=9
Multiplication: The Multiplication can be said the mathematical operation where one number is multiplied by another. The multiplication tricks are very important for fast calculation. Like 5X4=20
Division Tricks: The Division can be said Arithmetic Operation where a number is distributed equally. Like If a Bag has 9 Balls and we want to distribute equally in three persons then 9/3=3
Basic Math Tricks Aptitude Questions and Answers According to Previous Year Solved Papers:
Question 1: Find Out the Addition of Similar Digit Like 3+33+333+33333=?
Solution: In the very First step take 3 common and replace all 3 with 1
Count Number of Digits
Like 1=1, 11=2, 111=3, 11111=5
Taking Together= 1235
In the series 3 with four digit is missing. Take a imaginary 4 between 3 and 5. So the number will be 12345
Multiply 3X12345= 37035 Now Subtract 3333 from result we get
Question 2: Find out the addition of Similar Digit Like 5+55+555??
Solution: Take 5 Common and Replace all 5 with 1 like 5(1+11+111)
Count Number of Digits in each number and like 1=1, 11=2, 111=3 and write together
Question 3: Calculate the multiplication of two digit number like 43X63=??
Solution: Multiply 3X3=9 and Note 9
Do Cross Multiplication (4X3) =12 and (6X3)=18
Add both the results (4X3+6X3)=30 and write 0 to left of 9 and carry 3
Multiply left hand side numbers (4X6)=24 and add carry (24+3)=27 and write down to the left of 0 we get 2709
Question 4: Calculate the divisibility of a number by 2?. The number is 223344880
Solution: 223344880/2= 111672440
Question 5: Calculate the divisibility by 3 of a Number like 861??
Solution: Add all the digits
15 is divisible by 3 so number is divisible by 3
