Solve this Time and Work question: Vikas can finish a project in 24 days and Lokesh in 36 days. After working together for 6 days, Vikas leaves. How many additional days will Lokesh require?

Last Updated:

This bilingual Time and Work item asks the learner to solve “Solve this Time and Work question: Vikas can finish a project in 24 days and Lokesh in 36 days. After working together for 6 days, Vikas leaves. How many additional days will Lokesh require?” through a complete, auditable work-rate equation. The validated answer is 21 days. The explanation preserves the original question-specific working, reconstructs the governing rule, checks every relevant condition or transition, and compares all three distractors. It builds disciplined reasoning, accurate option elimination and exam-ready verification for SSC, Railway, Banking, Defence, State examinations and other competitive tests.

B23 days
C19 days

Explanation

The verified answer to “Solve this Time and Work question: Vikas can finish a project in 24 days and Lokesh in 36 days. After working together for 6 days, Vikas leaves. How many additional days will Lokesh require?” is 21 days, option D. The question-specific working supplied with the item states: work in 6 days = 6(1/24+1/36). The remaining work is divided by Lokesh's rate 1/36, giving 21 days.23 दिन 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 21 days. The alternatives 22 days, 23 days and 19 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 21 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.

Important Notes

  • Rebuild the complete Time and Work work-rate equation before selecting 21 days.
  • Question-specific Time and Work working connects the stated clues or terms directly with 21 days.
  • Options 22 days, 23 days, 19 days each break a condition or transition in this Time and Work item.
  • Replay every step in the Time and Work work-rate equation to independently confirm 21 days.

21 days, option D.

Which method solves this Time and Work item?

Rebuild and verify the complete work-rate equation.

22 days, 23 days, 19 days break a clue, direction, transition or operation.

How should the answer be checked?

Replay the rule from the first clue or term and test every intermediate step.

What is Time and Work and what is the basic concept?

Time and Work problems involve finding how long it takes to complete a task. Basic concept: If A can do a work in n days, A's one day work = 1/n. If A and B together can do work in n days, combined one day work = 1/n. Key formula: Total Work = Efficiency x Time. Time and Work is a major topic in SSC CGL, IBPS Bank PO, SBI PO, CAT, and Railway exams.

How to solve Time and Work problems using LCM method?

LCM Method: Assume total work = LCM of given days. Calculate each person's work per day = Total work divided by Days. Combined work per day = Sum of individual work rates. Time = Total work divided by Combined rate. Example: A can do work in 10 days, B in 15 days. LCM(10,15) = 30 units. A's daily work = 3 units, B's = 2 units. Together = 5 units/day. Time = 30/5 = 6 days. This avoids fractions and is much faster.
