Useful Maths Number system Shortcuts (For IBPS, SSC, GOVERNMENT EXAMS)

Useful Number system Shortcuts.
1. When Sum and Diff of two numbers (X and Y) are given,
X = (sum + diff)/2
Y = (sum – diff)/2
2. Diff between two digits of two
digit number is =(Diff in original and interchanged number)/9
3. Sum of first n odd nos is n2
4. Sum of first n even nos n(n+1)
5. Sum of squares of first n natural no’s is n(n+1)(2n+1)/6
6. Sum of cubes of first n natural numbers is [n(n+1)/2]2
7. If the sum of squares of two numbers is x and the square of their diff is y, then the product of the two numbers is [(x-y)/2]
*********Ratio and Proportion Short-cuts*********
1. If four quantities are in proportion, then Product of Means = Product of Extremes. In the proportion a:b::c:d, we have bc = ad
2. If a:b::c:x, x is called the fourth proportional of a, b, c. a/b = c/x or, x = bc/a.
3. If two numbers are in a:b ratio and the sum of these numbers is x, then numbers will be ax/ (a+b) and bx/(a+b) respectively
4. If three numbers are in the ratio a:b:c and the sum of these numbers is x, then these
numbers will be ax/(a+b+c) , bx/(a+b+c) and cx/(a+b+c) respectively
5. If the ratio of two numbers is a: b, then the numbers that should be added to each of the numbers in order to make this ratio c:d is given by (ad-bc)/(c-d)
6. If the ratio of two numbers is a:b, then the number that should be subtracted from each of the numbers in order to make this ratio c:d is given by (bc-ad)/(c-d)

In SSC CGL exam, it is very important that you solve maths’ questions quickly to score good marks.

1) Quantitative Aptitude For Competitive Examinations by R. S. Aggarwal One of the best book for basic Quantitative/Numerical Aptitude. It will help you learn all the basics of mathematics.

• So to get issue a debit card, one should have a bank account.
• This means that debit cards are only issued by banks which are linked to the customer’s bank account number.
• So, in the case to use a debit card, one should have enough balance in his bank account.
• They are used to withdraw cash from ATM, purchase of goods and services at Point of Sale (POS)/E-commerce (online purchase) both domestically and internationally (provided it is enabled for international use).
• It can also be used only for domestic fund transfer from one person to another.
► Credit Card
• Unlike debit cards, in case of credit cards, a customer can also withdraw beyond the amount of money present in his bank account.
• But there is a limit for each credit card up to which extra money can be withdrawn.
• And also there is a time limit up to which the extra money withdrawn should be paid back. This amount of money is paid back along with interest charges as applied by the issuer of card.
• They are issued by banks / other entities approved by RBI.

• These cards can be used domestically and internationally (provided it is enabled for international use).
• The credit cards can be used to withdraw cash from an ATM and for transferring funds to bank accounts, debit cards, credit cards and prepaid cards within the country.
► Prepaid Card
• The usage of prepaid cards depends on who has issued these cards. They can be issued by banks/non-banks.
• To get issue a prepaid card, the customer has to pay the amount in advance which is then stored in his prepaid card to be used whenever required.
• So a prepaid card is never linked to an account.
• The maximum value that can be stored in a prepaid card at any point of time is Rs 50,000.
• The prepaid cards issued by the banks can be used to withdraw cash from an ATM, purchase of goods and services at Point of Sale (POS)/E-commerce (online purchase) and for domestic fund transfer from one person to another. Such prepaid cards are known as open system prepaid cards.

How To Find Squares of Numbers ending in 5 Very Fast

Finding Squares of Numbers ending in 5 in less than 5 seconds!!!
The Square of numbers ending in 5 can be easily calculated in few seconds. In five seconds you will be able to solve in a single line.
The answer comes in two parts. LHS and RHS. The RHS is always 25. Because for all the numbers ending in 5, the last two digits of its square will be 25.
Example 1:
What is Square of 45?
Step 1: Divide 45 into 4 / 5.
Step 2 (LHS): The next consecutive digit of 4 is 5. So Multiply 4 with 5. ie 20.
Step 3: 20/Square of 5 ie 25 (RHS is always 25)
Answer is 2025.
Example 2:
What is the Square of 65?
Step 1: 6 / 5.
Step 2: 6 x 7 = 42. (LHS)
Step 3: 42 / 25
The Answer is 4225
Example 3:
What is the Square of 95?
Step 1: 9 / 5
Step 2: 9 x 10 = 90 (LHS)
Step 3: 90 / 25
The Answer is 9025
Square of 25 = 2 x 3 / 5 x 5 = 6 / 25 = 625.
Square of 125 = 12 x 13/ 5 x 5 = 156 / 25 = 15625.
Square of 505 = 50 x 51/ 5 x 5 = 2550 / 25 = 255025.
