Solve this Time and Work question: 30 workers plan to complete a warehouse task in 12 days. After 4 days, 8 additional workers join. How many more days are needed, assuming equal efficiency?

The verified answer to “Solve this Time and Work question: 30 workers plan to complete a warehouse task in 12 days. After 4 days, 8 additional workers join. How many more days are needed, assuming equal efficiency?” is 6.32 days, option C. The question-specific working supplied with the item states: rk = 30×12 worker-days. Work done = 30×4. The remaining work is divided among 38 workers, giving 6.32 days.8.32 दिन This working identifies the relevant work-rate equation and connects the given information to the required result. After applying the verified rule, the required value or position is 6.32 days. The alternatives 4.32 days, 5.32 days and 8.32 days fail because each breaks at least one stated condition, transition, direction or arithmetic step. A plausible-looking option is not sufficient unless it reproduces the complete work-rate equation. This full replay leads only to 6.32 days, so option C is uniquely correct. The method is transparent, question-specific and suitable for SSC, Railway, Banking, Defence, State and other competitive examinations.
