Tom takd 3 days to do a piece work while jerry take only one day for the same . Together. They both can finish the job in 15 days. In how many days tom will finish the work.

I think it is 5 days

Rong ans

ok what is it?

How many pieces can they do together in a day?

Tom = 1/3 piece/day
Jerry = 3/3 pieces/day
so together 4/3 piece per day
so how many pieces in the job?
4/3 piece/day * 15 days = 20 pieces
so how long would it tale Tome alone?
20 pieces * 3 days/piece = 60 days

Of course by then it may snow.

It's clear you copied this answer from another tutor since the day before you didn't know how to answer the question:

"This three times repeated question is worded incorrectly. Obviously either could do the job many times in 15 days".

I wonder how many other answers you copy, pretending you know it all.

To find out in how many days Tom will finish the work, we can first determine how much work Tom completes in one day and how much work Jerry completes in one day.

Let's assume that the total work is represented as 1. Since Tom takes 3 days to complete the work, we can say that Tom completes 1/3 of the work in one day. Similarly, Jerry completes 1/1 or the entire work in one day.

Now, let's calculate the combined work they can do in one day when working together. We are given that together, they can finish the job in 15 days. So, in one day, they complete 1/15th of the work.

Since we know that Tom completes 1/3 of the work in one day and Jerry completes the entire work in one day, we can set up the following equation:

1/3 + 1 = 1/15

To solve for the common denominator, we multiply each fraction by 15:

5 + 15 = 1

20 = 1
