1. Given ratio:

\frac{12 \text{ problems}}{42 \text{ minutes}}

2. Let $ x $ be the number of minutes to solve 20 problems:

\frac{20 \text{ problems}}{x \text{ minutes}}

3. Equate the ratios:

\frac{12}{42} = \frac{20}{x}

4. Cross-multiply:

12x = 42 \times 20

5. Solve for $ x $:

12x = 840

x = \frac{840}{12}

x = 70

Therefore, it will take $ x = 70 \text{ minutes} $.
