The verified answer to “Solve this Time and Work question: Yash can do a job in 20 days and Dev in 30 days. They work on alternate days, beginning with Yash. What percentage of the job is completed in 14 days?” is 58.33 %, option D. The question-specific working supplied with the item states: here are 7 working days of Yash and 7 of Dev. Completed work = 7/20+7/30 = 0.58, or 58.33%. This working identifies the relevant work-rate equation and connects the given information to the required result. To solve reliably, represent every term, person, seat, letter or operation in the order stated; then apply one rule consistently instead of guessing from the final pair alone. The alternatives 59.33 %, 60.33 % and 56.33 % 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. For independent confirmation, begin with the first clue or term, rebuild each intermediate step, and compare the derived result with all four choices. In an arrangement, check every positional clue against the completed map. In a letter series, translate letters into positions A=1 through Z=26 and preserve wraparound. The method is transparent, question-specific and suitable for SSC, Railway, Banking, Defence, State and other competitive examinations.
