Question

at 70% an engine produces 1250 hp, what is the max output hp? (nearest whole number)

Explanation:

Step1: Calculate percentage for first - question

Use the formula $\text{Percentage}=\frac{\text{Actual output}}{\text{Max output}}\times100$. Given actual output = 20 hp and max output = 300 hp. So, $\text{Percentage}=\frac{20}{300}\times100=\frac{2000}{300}\approx6.67$. Rounding to the nearest whole number gives 7.

Step2: Calculate max - output for second - question

Let the max output be $x$. We know that 70% of $x$ is 1250 hp. So, $0.7x = 1250$. Then $x=\frac{1250}{0.7}\approx1786$.

Answer:

7
1786
