Find the value of question mark(?) in the following questions ?
`1995+7xxsqrt?` = 3705

Options

A. 114
B. 169
C. 324
D. 18

Answer

To find the value of the question mark (?) in the equation:

\[ 1995 + 7 \times \sqrt{?} = 3705 \]

we can follow these steps:

### Step 1: Isolate the term with the square root
We start by moving 1995 to the right side of the equation:

\[ 7 \times \sqrt{?} = 3705 - 1995 \]

### Step 2: Calculate the right side
Now, we perform the subtraction:

\[ 3705 - 1995 = 1710 \]

So, we have:

\[ 7 \times \sqrt{?} = 1710 \]

### Step 3: Divide both sides by 7
Next, we divide both sides of the equation by 7 to isolate the square root:

\[ \sqrt{?} = \frac{1710}{7} \]

### Step 4: Calculate the division
Now, we perform the division:

\[ \frac{1710}{7} = 244.2857142857143 \approx 244.29 \]

So, we have:

\[ \sqrt{?} \approx 244.29 \]

### Step 5: Square both sides
To find the value of ?, we square both sides:

\[ ? = (244.29)^2 \]

### Step 6: Calculate the square
Now we calculate the square:

\[ ? \approx 244.29^2 \approx 59672.0641 \]

Thus, the value of the question mark (?) is approximately:

\[ ? \approx 59672.06 \]

### Final Answer:
The value of the question mark (?) is approximately 59672.06.
