A sum of money is to be distributed among P, Q, and R in the ratio 3:5:8. If R receives $1200 more than Q, what is the total sum of money distributed?

✓ Correct Answer: Option B

Let the shares be 3x, 5x, and 8x. R receives 8x and Q receives 5x. So, 8x - 5x = 1200, which means 3x = 1200, and x = 400. The total sum is 3x + 5x + 8x = 16x = 16 * 400 = $6400.
