Important Questions on Class 7 Maths Chapter 7
Find the ratio of ₹5 to 50 paise.
₹5 to 50 paise
= 5 x 100 paise to 50 paise [₹ 1 = 100 paise]
= 500 paise to 50 paise
Thus, the ratio = 500/50 = 10 : 1
I buy a T.V. for ₹10,000 and sell it at a profit of 20%. How much money do I get for it?
The cost price of T.V. = ₹ 10,000
Profit percent = 20%
Now,
Profit = Profit% of C.P. = 20/100 x 1000 = ₹ 2,000
Selling price = C.P. + Profit = ₹10,000 + ₹2,000 = ₹ 12,000
Hence, he gets ₹12,000 on selling his T.V.

About NCERT Solutions for Class 7 Maths Chapter 7
In 7 Mathematics Chapter 7 Comparing Quantities, we will study actually ratio and proportions in practical life. Some time we need to convert numbers into percentage. Percentages are numerators of fractions with denominator 100. Per cent is derived from Latin word ‘per centum’ meaning ‘per hundred’. Percentage when the total does not add to give 100. In the case, we multiply the fraction by 100/100. This does not change the value of the fraction. Subsequently, only 100 remains in the denominator. In this chapter we practice the questions based on –
1. Converting fraction into percent and vice versa.
2. Converting decimal into percent and vice versa.
3. Converting ratio into percent and percent into ratio also.
On the basis of percent, we can find the increase percent or decrease percent in any commodity to check the increase the cost percentage. The concepts of Cost price, Selling Price, Discount, Profit, Loss, etc. are based on the application of percentage. Simple Interest and Compound Interest are also the application in percentage.
1. The increase or decrease in a certain quantity can also be expressed as percentage.
2. When parts of a quantity are given to us as ratios, we have seen how to convert them to percentages.
Practice of Class 7 Maths Chapter 7
Practice with Percentages: Understand the concept of percentages and practice converting fractions and decimals to percentages and vice versa.
Solve Percentage Problems: Practice solving problems that involve calculating percentages of quantities, such as discounts, profit, and interest.
Use Ratios in Context: Apply ratios and proportions to solve real-world problems, such as scaling up recipes, calculating distances, or mixing solutions.
Work on Word Problems: Solve word problems that involve comparing quantities, percentages, and proportions. Focus on translating the problem into mathematical equations.
Use Online Resources: Look for online tutorials, videos, and interactive resources that explain and demonstrate these concepts. Create flashcards with ratios, proportions, and percentage conversions on one side and the corresponding solutions on the other.
Discuss with Peers: Collaborate with classmates to discuss concepts, solve problems together, and clarify doubts. Regularly review and revision to reinforce the understanding. This helps prevent forgetting important concepts.
