The verified answer to “Solve this Time and Work question: Meera and Pooja can audit a set of files in 20 days. Pooja and Nida can audit the same set in 30 days, while Nida and Meera can finish it in 40 days. The question-specific working supplied with the item states: Let Meera, Pooja and Nida have daily rates M, P and N. Then M + P = 1/20, P + N = 1/30, and N + M = 1/40. Add the first and third equations and subtract the second: 2M = 1/20 + 1/40 - 1/30. Hence Meera alone completes the audit in 48 days.

The verified answer to “Solve this Time and Work question: Rohit and Sameer can complete a project together in 10 days. Sameer and Imran can complete it in 12 days, while Imran and Rohit can complete it in 20 days. If Rohit works alone, how many days will he take to complete the project?” is 30 days, option D. The question-specific working supplied with the item states: Let the daily efficiencies of Rohit, Sameer and Imran be R, S and I. Then R + S = 1/10, S + I = 1/12, and I + R = 1/20. Add the first and third equations and subtract the second: 2R = 1/10 + 1/20 - 1/12. Rohit alone will complete the project in 30 days.

The verified answer to “Solve this Time and Work question: Arjun can build a boundary wall alone in 9 hours and Danish can build the same wall alone in 10 hours. When they work together, coordination delays reduce their combined output by 10 bricks per hour. Even then, they finish the wall in 5 hours. How many bricks are used in the wall?” is 900 bricks, option C. The question-specific working supplied with the item states: Let the wall contain N bricks. Arjun's hourly output = N/9 and Danish's hourly output = N/10. Their theoretical combined output is N/9 + N/10 = 19N/90 bricks per hour. Because coordination reduces production by 10 bricks per hour, actual output = 19N/90 - 10. They complete the wall in 5 hours, so actual output is N/5 = 18N/90. This gives N/90 = 10 and hence N = 900 bricks. 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 900 bricks. The alternatives 720 bricks, 810 bricks and 990 bricks 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.

The verified answer to “Solve this Time and Work question: Neha can complete a work in 10 days and Kavita can complete it in 15 days. They start together, but Neha leaves after some days. Kavita completes the remaining work, and the entire work is finished in 9 days. After how many days did Neha leave?” is 4 days, option B. The question-specific working supplied with the item states: Let Neha work for x days. Neha's one-day work = 1/10 and Kavita's one-day work = 1/15. Kavita works for all 9 days, so her completed work = 9/15 = 3/5. Remaining work = 1 - 3/5 = 2/5. This remaining 2/5 work was completed by Neha. Hence x = 10 × 2/5 = 4 days. So Neha left after 4 days. 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 4 days. The alternatives 3 days, 5 days and 6 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 4 days, so option B is uniquely correct.

The verified answer to “Solve this Time and Work question: Ravi can complete a work in 12 days and Mohan can complete the same work in 18 days. They start together, but Ravi leaves after 4 days. The question-specific working supplied with the item states: Total work = LCM of 12 and 18 = 36 units Ravi's one-day work = 36 ÷ 12 = 3 units. Mohan's one-day work = 36 ÷ 18 = 2 units. Together, they complete 3 + 2 = 5 units per day. Work completed in 4 days = 4 × 5 = 20 units. Remaining work = 36 − 20 = 16 units. After Ravi leaves, Mohan works alone at 2 units per day. Required time = 16 ÷ 2 = 8 days. Therefore, Mohan will finish the remaining work in 8 days. 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 8 days. The alternatives 10 days, 12 days and 6 days fail because each breaks at least one stated condition, transition, direction or arithmetic step.
