Answer

To convert the number "Two crore fifty-three lakh" into scientific notation, we will follow these steps:

### Step 1: Understand the number
- "Two crore" is equal to 2 x 10^7 (since 1 crore = 10^7).

### Step 2: Convert to a single number
- First, we convert "Two crore" to its numeric form:
- 2 crore = 2 x 10^7 = 20,000,000.
- Next, we convert "Fifty-three lakh" to its numeric form:
- 53 lakh = 53 x 10^5 = 5,300,000.

### Step 3: Add the two values
- Now, we add these two values together:
- 20,000,000 + 5,300,000 = 25,300,000.

### Step 4: Write in scientific notation
- To express 25,300,000 in scientific notation, we need to place the decimal point after the first non-zero digit:
- 25,300,000 = 2.53 x 10^7.

### Final Answer
