  4. D256Correct

Answer: D. 256

Explanation

Given: Two-thirds of half of the three-eighths of a number is 40 Calculation: Let the number be N According to the question, N × (3/8) × (1/2) × (2/3) = 40 ⇒ N × (1/8) = 40 ⇒ N = 320 So, the number is 320 Now, 80% of 320 = 320 × (80/100) ⇒ 256 ∴ 80% of that number is 256.
