Q. Which is the most accurate way to estimate 34%34\% of 2929?\newlineChoices:\newline(A) 34×28\frac{3}{4} \times 28\newline(B) 14×28\frac{1}{4} \times 28\newline(C) 23×30\frac{2}{3} \times 30\newline(D) 13×30\frac{1}{3} \times 30
  1. Calculate Percentage: Calculate 3434% of 2929 directly to compare with the choices.\newlineCalculation: 0.34×29=9.86 0.34 \times 29 = 9.86
  2. Evaluate Choices: Evaluate each choice to see which is closest to 99.8686.\newline(A) 34×28=21 \frac{3}{4} \times 28 = 21 \newline(B) 14×28=7 \frac{1}{4} \times 28 = 7 \newline(C) 23×30=20 \frac{2}{3} \times 30 = 20 \newline(D) 1/3×30=10 \frac{1/3} \times 30 = 10
  3. Compare Results: Compare the results from Step 22 with the direct calculation.\newlineChoice (D) 10 10 is closest to 9.86 9.86 .
