Marked price of a geyser =₹9000 Discounted price of the geyser =₹7560 Discount = ₹9000 – ₹7560 = ₹1440 $\therefore$ Required percentage reduction

$$ \begin{aligned} & =\frac{1440}{9000} \times 100 \% \\ & =16 \% \end{aligned} $$

Q. 3. Misha spent ` 15,000 for groceries and home products last month. She shopped online as well as from the local market.

Ans. Option (b) is correct.

Explanation :

Total amount spent on 20 pairs of earrings = 200 + 30 + 20 = 250 S.P. of 20 pairs of earrings = 20 × 40 = 800 So, Profit = S.P. – C.P. = 800 – 250 = 550

Q. 5. What percentage profit did Nisha make?

Frequently Asked Questions (FAQs) on Comparing Quantities Case Study

Q1: what is an equivalent ratio.

A1: An equivalent ratio is a ratio that represents the same relationship between quantities as another ratio, but in different terms. For example, the ratio 2:3 is equivalent to 4:6 and 6:9. Equivalent ratios are useful in scaling quantities up or down while maintaining the same proportional relationship.

Q2: How is a ratio different from a fraction?

A2: A ratio is a way to compare two quantities by division, indicating how many times one quantity is contained in another. A fraction, on the other hand, represents a part of a whole. While ratios compare two numbers, fractions describe a part of a single quantity.

Q3: How do you convert a fraction to a percentage?

A3: To convert a fraction to a percentage, multiply the fraction by 100 and add the percentage symbol (%).

Q4: What is the formula for calculating percentage increase or decrease?

A4: The formula for percentage increase or decrease is: Percentage Change $=\frac{\text { Change in Value }}{\text { Original Value }} \times 100$ For an increase, the change in value is positive, and for a decrease, it’s negative.

Q5: How do you calculate profit or loss percentage?

A5: The profit or loss percentage is calculated using the following formulas: Profit Percentage:

$$ \text { Profit } \%=\frac{\text { Profit }}{\text { Cost Price }} \times 100 $$ Loss Percentage: $$ \operatorname{Loss} \%=\frac{\text { Loss }}{\text { Cost Price }} \times 100 $$

Q6: Can you give an example of how to solve a word problem involving ratios?

A6: Sure! Suppose there are 120 boys and 80 girls in a school. The ratio of boys to girls is calculated as: Ratio = 120/80 = 3/2 This means for every 3 boys, there are 2 girls.
