A person can complete a job in 30 days. If he works for 10 days, what is the remaining work in percentage?

Step 1: Understand that the person can complete the entire job in 30 days.
Step 2: Calculate how much work the person does in one day. This is 1 job / 30 days = 1/30 of the job per day.
Step 3: Determine how much work the person completes in 10 days. This is 10 days * (1/30 of the job per day) = 10/30 = 1/3 of the job.
Step 4: Find out how much work is left after 10 days. Since he completed 1/3 of the job, the remaining work is 1 - 1/3 = 2/3 of the job.
Step 5: Convert the remaining work into a percentage. To do this, multiply (2/3) by 100 to get approximately 66.67%.
