Options

A. `2 : 3`
B. 1 : 2
C. `3 : 2`
D. `2 : 1`

Answer

To find the ratio of the production of scooters by factory P to that by factory T in 1985, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Production Values**:
- According to the problem, the production of factory P in 1985 is 20 scooters.
- The production of factory T in 1985 is 40 scooters.

2. **Set Up the Ratio**:
- The ratio of the production of factory P to factory T can be expressed as:
\[ \text{Ratio} = \frac{\text{Production of P}}{\text{Production of T}} = \frac{20}{40} \]

3. **Simplify the Ratio**:
- To simplify the ratio \( \frac{20}{40} \), we can divide both the numerator and the denominator by their greatest common divisor, which is 20:
\[ \frac{20 \div 20}{40 \div 20} = \frac{1}{2} \]

4. **Write the Final Answer**:
- Therefore, the ratio of the production of scooters by factory P to that by factory T in 1985 is:
\[ 1 : 2 \]

### Final Answer:
The ratio of the production of scooters by factory P to that by factory T in 1985 is \( 1 : 2 \).
