Anmol finds that he is twelfth from the right in a line of boys and fourth from the left, how many boys should be added to the line such that there are 35 boys in the line?

Options

A. 19
B. 13
C. 14
D. 20

Explanation

To solve the problem step by step, let's break down the information given and find the solution.

### Step 1: Understand the ranks
Anmol is:
- 12th from the right
- 4th from the left

### Step 2: Calculate the total number of boys in the line
To find the total number of boys in the line, we can use the formula:
\[ \text{Total boys} = (\text{Rank from left}) + (\text{Rank from right}) - 1 \]

Substituting the values:
\[ \text{Total boys} = 4 + 12 - 1 \]
\[ \text{Total boys} = 16 - 1 \]
\[ \text{Total boys} = 15 \]

### Step 3: Determine how many boys need to be added
We need to find out how many boys should be added so that there are 35 boys in total.

Let \( x \) be the number of boys to be added. We can set up the equation:
\[ 15 + x = 35 \]

### Step 4: Solve for \( x \)
To find \( x \), we can rearrange the equation:
\[ x = 35 - 15 \]
\[ x = 20 \]

### Conclusion
Anmol needs to add **20 boys** to the line so that there are a total of 35 boys.
