Question

Find $ 60\% $ of $ 210 $

Answer 1

Hint: To solve this problem, we need to know how to write a number in percentage. We can solve either by normal method or by finding the percentage of the whole number. We can solve this problem by two methods.

Complete step-by-step answer:
 This problem can also be solved by using the percentage method. To solve this by percentage method, there should be a better understanding of how we find the percentage. For that let’s start with a simple problem, for instance let’s take a problem, find $ 10\% $ of $ 100 $ ? $ 10\% $ of $ 100 $ will be $ 10 $ , which means $ 10\% $ of any number will be the number divided by $ 10 $ . For example, $ 10\% $ of $ 380 $ is $ 38 $ . And here for this problem it’s given that we need to find $ 60\% $ of $ 210 $ , first we need to divide $ 210 $ by $ 10 $ and then multiply it by 6, we will get the answer. In case, if the percentage is $ 40 $ , then multiply it by 4. This is one of the direct methods to find the solution for the percentage problem.
Let’s consider the given problem,
  $ x = 60\% \times210 $
Let the unknown value be $ x $ , the above number becomes,
  $ x = \dfrac{{60}}{{100}}\times210 $
  $
  x = 6\times21 \\
  x = 126 \;
   $
This is our required solution.
So, the correct answer is “ x = 126”.

Note: hough we have a number of methods to solve this problem, it is better to workout with the above-mentioned method and after solving a number of problems in this model, one can consider the method, which I have mentioned in the additional information. Solving problems in this method needs better understanding in the concept of percentage. Work as many problems as possible to crack these types of problems in a limited time period.
