Question
A can do a job in 26 days. B is 30% more efficient than A. In how many days can B alone do the same job?
Solution
Step 1: We know that A can do the job in 26 days.
Step 2: B is 30% more efficient than A. This means B can do 1.3 jobs in the time A does 1 job.
Step 3: So, the time B takes to do the job that A does in 26 days is 26/1.3.
Step 4: Calculate 26/1.3 to find the number of days B takes to do the job. The answer is approximately 20 days.
So, B alone can do the same job in approximately 20 days.
