Options

A. 20
B. 23
C. 30
D. 80

Answer

To find the approximate percent increase in the price of chocolate, we can follow these steps:

### Step 1: Identify the previous and new prices
- Previous price of chocolate (CP1) = Rs 540
- New price of chocolate (CP2) = Rs 660

### Step 2: Calculate the increase in price
- Increase in price = New price - Previous price
- Increase = CP2 - CP1
- Increase = 660 - 540 = Rs 120

### Step 3: Calculate the percent increase
- Percent increase formula:
\[ \text{Percent Increase} = \left( \frac{\text{Increase}}{\text{Previous Price}} \right) \times 100 \]
- Substituting the values:
\[ \text{Percent Increase} = \left( \frac{120}{540} \right) \times 100 \]

### Step 4: Simplify the fraction
- Simplifying \( \frac{120}{540} \):
- Both numbers can be divided by 60:
\[ \frac{120 \div 60}{540 \div 60} = \frac{2}{9} \]

### Step 5: Calculate the percentage
- Now, calculate \( \frac{2}{9} \times 100 \):
\[ \frac{2 \times 100}{9} \approx 22.22\% \]

### Step 6: Round to the nearest option
- The approximate percent increase is 22.22%. Among the given options, the closest value is 23%.

### Final Answer
- The approximate percent increase in the price of chocolate is **23%**.
