Explanation:

- P, Q, and R work together to complete the task.

- P's rate is 1/16 of the work per day.

- Q's rate is 1/24 of the work per day.

- R's rate is 1/48 of the work per day.

- Combine their rates: \( \frac{1}{16} + \frac{1}{24} + \frac{1}{48} \).

- Find a common denominator (48): \( \frac{3}{48} + \frac{2}{48} + \frac{1}{48} \).

- Add them together: \( \frac{6}{48} = \frac{1}{8} \).

- They complete the work together in 8 days.

- Calculate each person's share of the work:

- P's share is \( \frac{8}{16} = \frac{1}{2} \).

- Q's share is \( \frac{8}{24} = \frac{1}{3} \).

- R's share is \( \frac{8}{48} = \frac{1}{6} \).

- Total payment: Rs744.

- Share:

- P: \( \frac{1}{2} \times 744 = 372 \).

- Q: \( \frac{1}{3} \times 744 = 248 \).

- R: \( \frac{1}{6} \times 744 = 124 \).

- Option 4: Rs124 is correct.
