Show answer & explanation
Correct answer: A
Step 1: Calculate A's daily work rate.
A can complete the work in 14 days, so A's 1 day's work = 1/14.
Step 2: Calculate work done by A in 4 days.
Work done by A in 4 days = 4 × (1/14) = 4/14 = 2/7.
Step 3: Calculate the remaining work.
Total work is considered as 1.
Remaining work = 1 - (Work done by A)
Remaining work = 1 - (2/7) = (7 - 2)/7 = 5/7.
Final Answer: Option 1
