Answer

To solve the problem step by step, we will break it down into two parts: calculating the increase in salary due to a 16.66% increase and then calculating the new salary if it were increased by 33.33%.

### Step 1: Calculate the increase in salary due to a 16.66% increase

1. **Identify the original salary**:
- William's original monthly salary is Rs. 1140.

2. **Convert the percentage to a decimal**:
- 16.66% can be expressed as 16.66/100 or 0.1666.

3. **Calculate the increase**:
- Increase = Original Salary × Percentage Increase
- Increase = 1140 × (16.66/100)
- Increase = 1140 × 0.1666
- Increase = 190.824

4. **Round the increase**:
- The increase can be rounded to Rs. 190.

### Step 2: Calculate the new salary after a 33.33% increase

1. **Identify the percentage for the second part**:
- The second increase is 33.33%.

2. **Convert the percentage to a decimal**:
- 33.33% can be expressed as 33.33/100 or 0.3333.

3. **Calculate the new salary**:
- New Salary = Original Salary + (Original Salary × Percentage Increase)
- New Salary = 1140 + (1140 × (33.33/100))
- New Salary = 1140 + (1140 × 0.3333)
- New Salary = 1140 + 380.022
- New Salary = 1520.022

4. **Round the new salary**:
- The new salary can be rounded to Rs. 1520.

### Final Answers:
- The increase in salary due to a 16.66% increase is Rs. 190.
