Let's solve each part of the problem step by step.

Problem 1: Find the discount percent when selling price and marked price are given.
We use the formula for
discount percent:
$$
\text{Discount \%} = \left( \frac{\text{Marked Price} - \text{Selling Price}}{\text{Marked Price}} \right) \times 100
$$
#### a) Marked price = $45, Selling price = $41.31
$$
\text{Discount} = 45 - 41.31 = 3.69
$$
$$
\text{Discount \%} = \left( \frac{3.69}{45} \right) \times 100 = 8.2\%
$$
✔ So,
8.2%
#### b) Marked price = $100, Selling price = $82.50
$$
\text{Discount} = 100 - 82.50 = 17.50
$$
$$
\text{Discount \%} = \left( \frac{17.50}{100} \right) \times 100 = 17.5\%
$$
✔ So,
17.5%
#### c) Marked price = $200, Selling price = $150
$$
\text{Discount} = 200 - 150 = 50
$$
$$
\text{Discount \%} = \left( \frac{50}{200} \right) \times 100 = 25\%
$$
✔ So,
25%
#### d) Marked price = $100, Selling price = $65
$$
\text{Discount} = 100 - 65 = 35
$$
$$
\text{Discount \%} = \left( \frac{35}{100} \right) \times 100 = 35\%
$$
✔ So,
35%

Problem 2: Write the discount percent when the offer is shown on the tag.
#### a) Tag says "20% OFF"
This means the discount is directly given as
20%.
✔ So,
20%
#### b) Tag shows a circle with 1/4 shaded (i.e., 25% off)
A quarter of the circle is shaded → represents
25% off
✔ So,
25%
#### c) Watch image with "30% OFF" written
Clearly labeled as
30% off
✔ So,
30%
#### d) Sale tag says "Save 15%"
Means
15% discount
✔ So,
15%

Problem 3: What is the discount percent when the marked price is $80 and the sale price is $60?
Use the formula again:
$$
\text{Discount} = 80 - 60 = 20
$$
$$
\text{Discount \%} = \left( \frac{20}{80} \right) \times 100 = 25\%
$$
Now check the options:
a) 40%
b) 35%
c) 25%
✔
d) 10%
✔ Correct answer:
c) 25%
