Question
Estimate 81% of 36.
- 28
- 38
- 35
- 350
Hint:
When a certain quantity is divided into 100 equal parts and a certain part of it is to be expressed in terms of the whole quantity, that portion is called as a percent, represented with a % sign.
Eg.- If we have 1,000 as the number of students in class 12th in a certain college with 700 inhouse students and 300 new entrants and we want to represent the number of inhouse students and new entrants as a percentage of the total population, we divide 1,000 in 100 equal parts i.e. 1,000/100, we get 1% = 10. Hence, inhouse students and new entrants are 70% (10*70 i.e. 700) and 30% (10*30 i.e. 300), respectively.
The correct answer is: 28
To find- 81% of 36.
Solution-
We know that 81% can be written as 81/100.
∴ 81% of 36 = 81/100 * 36
∴ 81% of 36 = 29.16 ≈ 28
Final Answer- Option 'a' i.e. '28' is the correct answer to the given question.
