Three workers A, B, and C are assigned tasks with the following details:

| Person | Work Done (units) | Maximum Time Allowed (hours) |
|--------|-------------------|------------------------------|
| A | 50 | 10 |
| B | 60 | 12 |
| C | - | 15 |

If worker B increases his working efficiency by 60% over his minimum efficiency, what is the total rest time taken by B during his entire work period?

Question

Three workers A, B, and C are assigned tasks with the following details:

| Person | Work Done (units) | Maximum Time Allowed (hours) |
|--------|-------------------|------------------------------|
| A      | 50                | 10                           |
| B      | 60                | 12                           |
| C      | -                 | 15                           |

If worker B increases his working efficiency by 60% over his minimum efficiency, what is the total rest time taken by B during his entire work period?

Accepted Answer

**Solution:**

1. Calculate B's minimum efficiency:
   - B does 60 units of work in maximum 12 hours.
   - Minimum efficiency = $ $\frac{60}{12} = 5 $$ units/hour.

2. B increases efficiency by 60%:
   - Increased efficiency = $$ 5 + 0.6 \times 5 = 5 + 3 = 8 $$ units/hour.

3. Calculate actual working time of B at increased efficiency:
   - Time taken = $ $\frac{60}{8} = 7.5 $$ hours.

4. Total time allowed for B is 12 hours.

5. Rest time = Total time - Actual working time = $ 12 - 7.5 = 4.5 $ hours.

**Answer:** 4.5 hours
