Understanding the Expression
The expression we need to evaluate is:
(√339 × 25) ÷ 30
We'll break it down step by step.
Step 1: Calculate the Square Root
- First, we find the square root of 339.
- Although 339 is not a perfect square, we can approximate it.
Step 2: Multiply by 25
- Next, we multiply the result of the square root by 25.
- To simplify our calculations, we can work with an approximation:
√339 ≈ 18.4
- Therefore, we calculate:
18.4 × 25 = 460
Step 3: Divide by 30
- Now, we divide our result by 30:
460 ÷ 30 ≈ 15.33
Final Calculation
- Since we are looking for an integer answer, we round down the result to the nearest whole number.
- However, this approximation suggests we should check our calculations.
Verifying the Options
- The options provided are:
- a) 12
- b) 15
- c) 24
- d) 21
- e) 9
- Given our calculations, the closest and most appropriate option is 15, which confirms that option 'B' is indeed the correct answer.
Conclusion
- Thus, (√339 × 25) ÷ 30 is approximately equal to 15.
