Answer:
It takes 1 seconds for push-ups and 3 seconds for sit-ups for Mei to do exercise.
Step-by-step explanation:
Given:
Let the time taken for push-ups be 'x'.
Let the time taken for sit-ups be 'y'.
Now Given:
17 push-ups and 6 sit-ups, it takes a total of 35 seconds.
So we can say that;

Also Given:
41 seconds to do 20 push-ups and 7 sit-ups.
so we can say that;

Now Multiplying equation 1 by 7 we get;

Now Multiplying equation 2 by 6 we get;

Now Subtracting equation 3 from equation 4 we get;

Now substituting the value of x in equation 1 we get;

Hence It takes 1 seconds for push-ups and 3 seconds for sit-ups for Mei to do exercise.
