Tips and Tricks to Solve Approximation Questions

The Quantitative Aptitude segment of the competitive exams comprises a vital part called Approximation. Candidates need to practice these questions while preparing for the examination.

Significance of Approximation in Exams?

• You can expect 5-10 Approximation inquiries in each bank test, particularly in the prelims stage.
• These inquiries are very simple to settle assuming that you have polished well on your Calculation speed.
• You can settle every one of the inquiries within 3-4 minutes with 100 percent exactness.
• These inquiries can build your possibilities by clearing the test.

What is Approximation?

An approximation is a cycle by which complex mathematical articulation are separated into less difficult structures by performing different numerical activities as indicated by the BODMAS rule.

In numerical expression, which incorporates division and multiplication of decimal values of huge numbers, it turns out to be very difficult to settle these expressions. thus, to decrease this difficulty we use Approximation techniques. in the Approximation strategy, we need not compute the exact value of an expression, yet we work out the closest Values (round-off values). at the point when we use the Approximation strategy, the eventual outcome acquired isn’t equivalent to the specific outcome yet it is extremely close either minimal less or minimal more to the last result.

BODMAS:

B →  Brackets 

O → Of

D → Division

M → Multiplication

A → Addition

S → Subtraction

Order of BODMAS Rule

Here are the ways to carry out the BODMAS rule in Approximation questions:

Step 1: Identify the brackets, start computation by solving brackets in this order (), {} and [] should be followed.

Step 2: Calculate the Powers and roots.

Step 3: Calculate Division and Multiplication (from left to right as both Multiplication and Division have the same priority)

Step 4: Calculate Addition and  Subtraction (from left to right as both Addition and  Subtraction have the same priority).

Approximation is a mathematical process that involves finding an estimate or approximation of a given value or expression. It is a valuable skill, particularly in Quantitative Aptitude tests, and is frequently used in competitive exams such as the SBI Clerk Mains, UPSC, PSC, and Railways. In fact, up to 10% of the total marks in these examinations may be dedicated to approximation questions. These questions are typically straightforward and can be solved quickly with a bit of practice. This article will provide an overview of approximation questions, their importance in competitive exams, and some tips and tricks for tackling them successfully. By the end of this article, you’ll have a better understanding of how to approach approximation questions and improve your chances of success in these exams.
