The verified answer to “Solve this Time and Work question: Worker earns Rs 200 per day and works for 12 days. If he rests 1 day per 4 working days, total earnings?” is 2400, option B. The question-specific working supplied with the item states: 12 working days x Rs 200 = Rs 2400. 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 2400. The alternatives 2200, 2000 and 1800 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 2400, so option B is uniquely correct. The method is transparent, question-specific and suitable for SSC, Railway, Banking, Defence, State and other competitive examinations.

The verified answer to “Solve this Time and Work question: A and B can do work in 10 days and 12 days. After working together for 4 days, A left. How many days for B to complete?” is 3.6 days, option D. The question-specific working supplied with the item states: In 4 days together: 4(1/10+1/12) = 4x11/60 = 44/60. Remaining work = 1 - 4(1/10+1/12) = 1 - 4(11/60) = 1-44/60 = 16/60. Days = (16/60)/(1/12) = 192/60 = 3.2 days. Let us round: 16/60 x 12 = 192/60 = 3.2 days.
