tips and tricks simplification

Simplification plays a vital role in the quantitative aptitude section of Bank Exams. It is one the most scoring section. Candidates who are applying for IBPS Exam should prepare tips and tricks for simplification section in bank examthis section properly to qualify through the overall as well as the sectional cut-off. Simplification questions are easy and take less time to solve.

To solve this simplification section the candidates must be well acquainted with the BODMAS rule:
B – Brackets []
O – Of
D – Division
M – Multiplication
A – And (Addition)
S – Subtraction
Topics in simplification section are:
Number System
Square & cube
HCF & LCM
Surds & Indices
Fractions & Decimals

Number System: this is the basis of quantitative ability which is to be attempted first. All counting numbers are termed as natural numbers. To solve these type of question the basic definitions of the number system and the division methods along with the divisible factors need to known properly. These are very simple if the roots of any numerical are known to the candidate. The division remainder rules, sum rules and the divisibility are to be solved with attention because candidate generally loses marks due to their silly mistakes. For example:

890 – 696 ÷ 3=?
32.33
658
-547.6
68.508
None of these
Answer: (2)
Solution: By BODMAS rule.

Square & Cube: This includes square root, cube root and factorization as well. Practice is required to master this section. The basic concept of perfect square numbers which are 1,4,9,6,5 and non-perfect square numbers like 2,3,7,8 are to be known. The square root and cube of the numbers including the factorization method should be at the tip. Practice will ensure faster calculation along with accuracy so that the time and accuracy in the time of the upcoming bank exam are perfect. For example: square root of 9 is 3. Cube root of 27 is 3.

HCF & LCM: there are basically two methods to solve problems on HCF & LCM which are factorization method and division method. In factorization method, each number has to be the product of the prime factors. Then the product of least powers gives the HCF.

Forexample: HCF of 108,288,360 108 gives [latex]2^{2} \times 3^{3}[/latex] , 288 gives [latex]2^{5} \times [/latex] 32 and 360 gives [latex]23 \times 5 \times 32[/latex]

HCF is 22 x 32= 36

Solution: 36 by factorization method
To find theLCM of 6,12,18,24 = 2 x 3 x 3 x 2 x 2 x 3 x 1 which is 72.

Solution: 72 by division method

 

Surds and Indices 

this section is all about remembering the different laws of surds and indices to solve the problems. The candidate needs to be well versed with the formulas. This section is almost like arithmetic formulas without those the problems cannot be solved. It will be better if the candidate makes a note of these rules and revise it daily through some problem which will help them to increase their efficiency in solving this kind of sums.

For example: Rule of indices like [latex]a^{m} \times a^{n} = a^{m+n}[/latex]

Rule of surds like [latex]\sqrt[n]{a} = a^{\frac{1}{n}}[/latex]

Fractions and Decimals: this section consists of different types of decimal and fraction which is to be known properly to solve the sums from this section. The candidates are advised to practice through previous years question paper so that they will be well acquainted with what type of questions are likely to come from this section. Mock test papers will also help to practice with accuracy.
For example: Multiplication of a decimal- 0.06 x 0.3 0.40 = 0.00720
Conversion of decimal into fraction – 0.16 = (16-1)/90 = 1/6

The simplification techniques are easy to practice so to score good marks this section must not be ignored. This section needs to be cleared first keeping all the tips in mind.
