What is the number of unsuccessful candidates in city D?

Answer

To find the number of unsuccessful candidates in city D, we can follow these steps:

### Step 1: Understand the given data
We need to analyze the table that provides information about the number of candidates in city D, including the ratio of candidates passing and failing.

### Step 2: Identify the total number of candidates in city D
From the table, we see that the total number of candidates in city D is given as 2.27 lakh.

### Step 3: Determine the ratio of passing and failing candidates
The problem states that the ratio of passing to failing candidates in city D is 1:3. This means for every 1 passing candidate, there are 3 failing candidates.

### Step 4: Calculate the total parts in the ratio
The total parts in the ratio of passing to failing candidates is:
- Passing: 1 part
- Failing: 3 parts
- Total: 1 + 3 = 4 parts

### Step 5: Calculate the number of failing candidates
To find the number of failing candidates, we can use the following formula:
\[ \text{Number of failing candidates} = \left(\frac{\text{Number of failing parts}}{\text{Total parts}}\right) \times \text{Total number of candidates} \]
Substituting the values we have:
\[ \text{Number of failing candidates} = \left(\frac{3}{4}\right) \times 2.27 \text{ lakh} \]

### Step 6: Perform the calculation
First, we convert 2.27 lakh to a numerical value:
\[ 2.27 \text{ lakh} = 2.27 \times 100000 = 227000 \]
Now, we can calculate the number of failing candidates:
\[ \text{Number of failing candidates} = \left(\frac{3}{4}\right) \times 227000 = \frac{681000}{4} = 170250 \]

### Step 7: Convert back to lakh
To express this in lakh, we divide by 100000:
\[ 170250 \div 100000 = 1.7025 \text{ lakh} \]

### Final Answer
The number of unsuccessful candidates in city D is **1.7025 lakh**.
