Question

Which of the following options is the closest approximate value which will come in place of question mark (?) in the following equation?

48.9 × 3.95 – 2.97 + 17.86 = ?

• A. 125
• B. 140
• C. 211
• D. 250

Answer 1

Answer:

C. 211

Round each decimal value to the nearest whole integer first to solve it quickly without a calculator:

• $48.9 \approx 49$

• $3.95 \approx 4$

• $2.97 \approx 3$

• $17.86 \approx 18$

Now apply BODMAS rules to the rounded integers:

1. Multiply: $49 \times 4 = 196$

2. Subtract: $196 - 3 = 193$

3. Add: $193 + 18 = \mathbf{211}$
