Originally peter was completing 4 sit ups for every 4 push ups but then he injured his shoulder after the injury peter completed the same number of the repetition as he did before his injury but he completed 6 sit ups for every 2 push ups during a training session after his injury peter completed 8 push ups how many push ups was peter doing before his injury

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
