Q
Q: A man can complete a work in 10 days. If he works for 3 days, how much of the work is left?
Solution: Work done in 3 days = 3/10. Work left = 1 - 3/10 = 7/10 = 70%.
Steps: 5
Step 1: Understand that the man can complete the entire work in 10 days.
Step 2: Calculate how much work he does in one day. Since he completes the work in 10 days, he does 1/10 of the work in one day.
Step 3: Calculate how much work he does in 3 days. Multiply the work done in one day (1/10) by 3 days: 3 * (1/10) = 3/10.
Step 4: Determine how much work is left. The total work is considered as 1 (or 100%). So, subtract the work done (3/10) from the total work (1): 1 - 3/10 = 7/10.
Step 5: Convert the remaining work into a percentage. 7/10 is equal to 70%.
