Solve this Time and Work question: Aman works every day and can finish a job in 10 days. Bharat, who can finish it in 15 days, helps on every third day. What percentage of the job is completed in 6 days?

Last Updated:

This bilingual Time and Work item asks the learner to solve “Solve this Time and Work question: Aman works every day and can finish a job in 10 days. Bharat, who can finish it in 15 days, helps on every third day. What percentage of the job is completed in 6 days?” through a complete, auditable work-rate equation. 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.

A73.33 %
B72.33 %
C74.33 %
D75.33 %
Correct Answer: 73.33 %Your Answer: A

Explanation

The verified answer to “Solve this Time and Work question: Aman works every day and can finish a job in 10 days. Bharat, who can finish it in 15 days, helps on every third day. The question-specific working supplied with the item states: orks 6 days and Bharat works 2 days. Total work = 6/10+2/15 = 0.73, or 73.33%.75.33% This working identifies the relevant work-rate equation and connects the given information to the required result. The alternatives 72.33 %, 74.33 % and 75.33 % 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. 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 73.33 %.
  • Question-specific Time and Work working connects the stated clues or terms directly with 73.33 %.
  • Options 72.33 %, 74.33 %, 75.33 % 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 73.33 %.

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.
