What approximate value will come in place of the (You are not expected to calculate the exact value.) question mark (?) in the following questions?
75% of 230 - ? = 64% of 249
Answer: A. 14 — Explanation (step-by-step): We are given 75% of 230 − ? = 64% of 249, so ? = 75% of 230 − 64% of 249. Compute 75% of 230: 0.75 × 230 = 172.5. Compute 64% of…

Correct answer: A
Explanation (step-by-step): We are given 75% of 230 − ? = 64% of 249, so ? = 75% of 230 − 64% of 249.
Compute 75% of 230: 0.75 × 230 = 172.5.
Compute 64% of 249: 0.64 × 249 = 159.36.
Subtract to find ?: 172.5 − 159.36 = 13.14.
Round as an approximate value: 13.14 ≈ 14.
Therefore the best approximate value for the question mark is 14.
