Math Problem Statement

if a does 33 by 1/3 % of the work in 17 days then in how many days whole work will be completed

Solution

To solve this problem, we need to determine how long it would take for AA to complete the entire work based on the given information.

Step 1: Determine the fraction of work done by AA.

  • AA completes 13%\frac{1}{3} \% of the work in 17 days.
  • 13%\frac{1}{3} \% can be written as 13×100=1300\frac{1}{3 \times 100} = \frac{1}{300}.

This means AA does 1300\frac{1}{300} of the total work in 17 days.

Step 2: Determine the work rate of AA.

  • Work rate RR is given by work done per day.
  • R=Work doneTime taken=130017=1300×17R = \frac{\text{Work done}}{\text{Time taken}} = \frac{\frac{1}{300}}{17} = \frac{1}{300 \times 17}.

Step 3: Calculate the time required to complete the whole work.

  • To complete the whole work, AA would need TT days, where: T=Total WorkWork rate=11300×17=300×17=5100 daysT = \frac{\text{Total Work}}{\text{Work rate}} = \frac{1}{\frac{1}{300 \times 17}} = 300 \times 17 = 5100 \text{ days}

So, AA would take 5100 days to complete the whole work.

  1. If BB does 25% of the work in 20 days, how long will BB take to complete the whole work?
  2. What is the work rate of a person who completes 10% of a task in 5 days?
  3. If CC can complete the entire work in 30 days, how much work does CC complete in 10 days?
  4. Two people can complete a task together in 15 days. If one person works twice as fast as the other, how long would each take to complete the work alone?
  5. If a task is 60% complete and 12 days have passed, how long will it take to finish the remaining work at the same rate?
  6. How would the time change if AA worked 10% faster on the same task?
  7. If the work rate doubles, how many days will it take to complete a task that originally took 20 days?
  8. What fraction of the work is done after 25 days if a person completes the work in 100 days?

Tip: When dealing with work problems, it’s often useful to express rates as fractions of the whole task and to set up equations that relate these rates to time.
