Solve this Time and Work question: A and B working together complete work in 6 days. A alone completes in 10 days. B was absent for 2 days. Total days?

The verified answer to “Solve this Time and Work question: A and B working together complete work in 6 days. A alone completes in 10 days. B was absent for 2 days. Total days?” is 7.5 days, option D. The question-specific working supplied with the item states: B alone = 15 days. When B absent 2 days, those 2 days only A works = 2/10 = 1/5 work done. Remaining = 4/5 done together at 1/6/day. Days = 24/5 = 4.8. Let me solve differently. Let total days = D. Actually A and B together D days - B absent 2 days means for 2 days only A works. Together days = D-2. 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 7.5 days. The alternatives 8 days, 6.5 days and 9 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 7.5 days, so option D is uniquely correct. The method is transparent, question-specific and suitable for SSC, Railway, Banking, Defence, State and other competitive examinations.
