Ankita bought a mobile phone for Rs. 2350 and sold it for Rs. 2538. Find her gain and gain per cent.

Answer

To solve the problem step by step, we will calculate Ankita's gain and gain percent from the sale of the mobile phone.

### Step 1: Identify the Cost Price (CP) and Selling Price (SP)
- **Cost Price (CP)**: Rs. 2350
- **Selling Price (SP)**: Rs. 2538

### Step 2: Calculate the Gain
The formula for Gain is:
\[ \text{Gain} = \text{Selling Price} - \text{Cost Price} \]

Substituting the values:
\[ \text{Gain} = 2538 - 2350 \]
\[ \text{Gain} = 188 \text{ Rs.} \]

### Step 3: Calculate the Gain Percent
The formula for Gain Percent is:
\[ \text{Gain Percent} = \left( \frac{\text{Gain}}{\text{Cost Price}} \right) \times 100 \]

Substituting the values:
\[ \text{Gain Percent} = \left( \frac{188}{2350} \right) \times 100 \]

### Step 4: Simplify the Calculation
First, calculate \( \frac{188}{2350} \):
- Dividing 188 by 2350 gives approximately 0.08.

Now multiply by 100:
\[ \text{Gain Percent} = 0.08 \times 100 = 8\% \]

### Final Result
- **Gain**: Rs. 188
- **Gain Percent**: 8%
