Raju : Dada, I can see this sign % after 58 in the picture above. And it’s there also after          
43 in the other picture. What does it show?
Dada : That is the sign for percentage. The word cent means hundred. We read 58% as          
‘58 percent’.
Raju : Then, what does percentage mean?
Dada : In the first picture, there is 58% water in the dam. It means that if the dam holds 
100 units of water when full, then right now it is holding 58 of the same units of 
water. If the mobile phone has 100 units of charge when it is fully charged, then 
at this moment 43 units of charge are still left. A percentage is a comparison made 
with a total which is taken to be 100 parts. 
Raju : If there is 50% water in the dam, can we say that the dam is half full?
Dada : Yes, 50% is 50 parts of water out of 100, and half of 100 is 50.
58% is 58 units out of 100 units. We can write this as the fraction 
58
100
.
It means that 
58
100
 parts out of the full capacity of the dam are filled with water.
(1) Percentage in the Form of a Fraction
50% means 50 parts of a total of 100. So, 50 out of 100 or
50

 =

In other words, 50% is half of the whole.

Example : Last year Giripremi group planted 75 trees. Of these, 48 trees flourished. The 
Karmavir group planted 50 trees, of which, 35 flourished. Which group was 
more successful in conserving the trees they had planted?
   The number of trees each group started with is different. Hence, we have to 
compare the surviving trees in each group to the number of trees planted by 
them. For this comparison, it would be useful to find out for each group, the 
percentage of their trees that survived. To do that, let us find the ratio of the 
number of surviving trees to the total trees planted. 
   Suppose the surviving trees of the the Giripremi group are A%.
   Suppose the surviving trees of the the Karmavir group are B%.
   The Giripremi’s ratio of the surviving trees to planted trees is  
A

 and also 
48

. Therefore, 
A

 =

. In the same way, we can also find the ratio of 
surviving trees to planted trees for the Karmavir group. 
   Let us write the same ratio in two forms, obtain equations and solve them.

Example :  In Khatav taluka, it was decided to make 200 ponds in Warudgaon and 300 
ponds in Jakhangaon. Of these, 120 ponds in Warudgaon were completed at 
the end of May, while in Jakhangaon work was complete on 165 ponds. In 
which village was a greater proportion of the work completed?
   To find the answer, we shall find the percentage of work completed in each 
village and then make a comparison.
   Let the number of ponds completed in Warudgaon be A% and in Jakhangaon, 
B%. We shall find the ratio of the number of ponds completed to the number

FAQs on Textbook: Percentage - Mathematics Class 6 (Maharashtra Board)

1. What is a percentage and how is it used in everyday life?
Ans. A percentage is a way of expressing a number as a fraction of 100. It is often used to compare values, find discounts, calculate grades, and understand statistics. For example, if you score 45 out of 50 on a test, you can express your score as a percentage by calculating (45/50) * 100, which equals 90%. This shows that you scored 90% on your test.
2. How do you calculate a percentage of a number?
Ans. To calculate a percentage of a number, you multiply the number by the percentage expressed as a decimal. For instance, to find 20% of 150, you convert 20% to a decimal (0.20) and then multiply: 150 * 0.20 = 30. Therefore, 20% of 150 is 30.
3. What is the difference between a percentage increase and a percentage decrease?
Ans. A percentage increase refers to the amount an original value has grown, expressed as a percentage of that original value. For example, if a shirt costs $50 and is marked up to $60, the percentage increase is [(60 - 50) / 50] * 100 = 20%. Conversely, a percentage decrease shows how much a value has reduced compared to the original. If the shirt is then sold for $40, the percentage decrease is [(50 - 40) / 50] * 100 = 20%.
4. How can percentages be used to calculate discounts during sales?
Ans. Percentages are commonly used to express discounts. To calculate a discount, you first find the percentage of the original price and then subtract that amount from the original price. For example, if a pair of shoes costs $80 and there is a 25% discount, you would calculate the discount amount as (25/100) * 80 = $20. Thus, the sale price would be $80 - $20 = $60.
5. Why is understanding percentages important for students?
Ans. Understanding percentages is crucial for students because it helps them make informed decisions in various aspects of life, such as finance, shopping, and academics. Percentages are used in calculating grades, understanding interest rates, analyzing data, and interpreting results in surveys. A strong grasp of percentages enables students to solve real-life problems effectively.
