What will come in the place of (?) mark in following question.
`(sqrt(144) + sqrt(169)) xx 3 = (?)/(5)`

Options

A. 375
B. 325
C. 350
D. 275

Answer

To solve the equation \((\sqrt{144} + \sqrt{169}) \times 3 = \frac{?}{5}\), we will follow these steps:

### Step 1: Calculate \(\sqrt{144}\)
\[ \sqrt{144} = 12 \]

### Step 2: Calculate \(\sqrt{169}\)
\[ \sqrt{169} = 13 \]

### Step 3: Add the results from Step 1 and Step 2
\[ \sqrt{144} + \sqrt{169} = 12 + 13 = 25 \]

### Step 4: Multiply the sum by 3
\[ 25 \times 3 = 75 \]

### Step 5: Set up the equation to find the question mark
We have:
\[ 75 = \frac{?}{5} \]

### Step 6: Solve for the question mark
To find the value of \(?\), we multiply both sides by 5:
\[ ? = 75 \times 5 = 375 \]

Thus, the value that comes in place of the question mark is \(375\).

### Final Answer:
\[ ? = 375 \]
