Question: Given a daily rate of ₱840.00 and a basic hourly rate of ₱105.00, find the overtime rate of overtime pay on an ordinary working day,
1. **State the problem:** We need to find the overtime rate of pay given a daily rate of 840 and a basic hourly rate of 105.
2. **Recall the formula:** The overtime rate on an ordinary working day is usually 1.25 times the basic hourly rate.
3. **Calculate the overtime rate:**
$$\text{overtime rate} = 1.25 \times \text{basic hourly rate}$$
$$= 1.25 \times 105$$
4. **Perform the multiplication:**
$$= 131.25$$
5. **Interpretation:** The overtime rate of pay on an ordinary working day is 131.25 per hour.
**Final answer:**
$$\boxed{131.25}$$
