The verified answer to “Solve this Time and Work question: The efficiency ratio of Anita to Poonam is 7:9. If Anita completes a job in 27 days, how many days will Poonam take?” is 21 days, option B. The question-specific working supplied with the item states: s inversely proportional to efficiency. Therefore Anita:Poonam time ratio is 9:7, and Poonam's time = 27×7/9 = 21 days.21 दिन 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. After applying the verified rule, the required value or position is 21 days. The alternatives 22 days, 19 days and 20 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. For independent confirmation, begin with the first clue or term, rebuild each intermediate step, and compare the derived result with all four choices. In a letter series, translate letters into positions A=1 through Z=26 and preserve wraparound. This full replay leads only to 21 days, so option B is uniquely correct. The method is transparent, question-specific and suitable for SSC, Railway, Banking, Defence, State and other competitive examinations.
