Each boy's earnings is divided by 500 to find the percentages.
To find the percentage of the job that each boy did, you need to divide the amount each boy earned by the total amount earned and then multiply by 100.
Let's break it down step by step with the given information:
1. Start by adding up the amounts earned by the pairs:
- Tony and Ted earned 280.
- Ted and Tom earned 260.
- Ted and Terry earned 220.
2. Next, add up all the amounts earned to find the total amount earned:
Total = 280 + 260 + 220 = 760.
3. Now, calculate the percentage of the job that each boy did:
- For Tony: Tony's earning is given, so Tony's percentage = (Tony's earning / Total) x 100.
- For Ted: Since Ted's earnings are involved in all three pairs, you'll need to subtract the amount earned in each pair from the total. Then, calculate Ted's percentage using the same formula.
- Repeat the same steps for Tom and Terry.
Let's calculate the percentages for each boy using this method:
1. Tony's percentage: (280 / 760) x 100 = 36.84%
2. Ted's percentage: ((260 + 280 + 220) / 760) x 100 = 86.84%
3. Tom's percentage: (260 / 760) x 100 = 34.21%
4. Terry's percentage: (220 / 760) x 100 = 28.95%
So, Tony did 36.84% of the job, Ted did 86.84% of the job, Tom did 34.21% of the job, and Terry did 28.95% of the job.
