नीचे दिए गए प्रश्न मे प्रश्नवाचक चिन्ह (?) के स्थान पर लगभग कितना मान आएगा?
`sqrt(1156.04)xx 17.97 + ? div 23 = 630.97 `

Options

A. 300
B. 380
C. 350
D. 437

Answer

To solve the equation given in the question, we will follow these steps:

1. **Identify the equation**: We have the equation
\[ \sqrt{1156.04} \times 17.97 + ? \div 23 = 630.97 \]

2. **Calculate the square root**: First, we need to find the square root of 1156.04.
\[ \sqrt{1156.04} \approx 34 \]

3. **Substitute the square root value**: Now we can substitute this value back into the equation:
\[ 34 \times 17.97 + ? \div 23 = 630.97 \]

4. **Calculate the multiplication**: Next, we calculate \(34 \times 17.97\):
\[ 34 \times 17.97 \approx 610.98 \]

5. **Rewrite the equation**: We can now rewrite the equation with this value:
\[ 610.98 + ? \div 23 = 630.97 \]

6. **Isolate the question mark term**: To isolate the term with the question mark, we subtract 610.98 from both sides:
\[ ? \div 23 = 630.97 - 610.98 \]
\[ ? \div 23 = 19.99 \]

7. **Multiply to find the question mark**: Finally, we multiply both sides by 23 to find the value of the question mark:
\[ ? = 19.99 \times 23 \]
\[ ? \approx 459.77 \]

8. **Round to the nearest whole number**: Since the question asks for an approximate value, we can round this to:
\[ ? \approx 460 \]

Thus, the approximate value that will come in place of the question mark (?) is **460**.
