anurag can finish painting a wall in 4 days. Ravi can do the same work in 12 days. How long would they take if they both paint the wall together

Same length is comparing because it’s saying its the same and not different

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.
