Show answer & explanation

Correct answer: C

Answer: 384

Explanation:

  1. Compute each boy's marks:

  2. 64% of 800 = 0.64 × 800 = 512

  3. 36% of 800 = 0.36 × 800 = 288

  4. 44% of 800 = 0.44 × 800 = 352

  5. Sum of marks = 512 + 288 + 352 = 1152

  6. Average = 1152 ÷ 3 = 384

Therefore, the average mark scored by the three boys is 384.
