1. Work Rate

If a person completes a work in n days, one day's work is 1/n.

\[\boxed{1\ day\ work=1/n}\]
Solved Example

Question: A completes work in 10 days

  1. Identify the given values carefully.
  2. Write the required formula.
  3. Substitute the values step by step.
  4. Simplify the calculation.
  5. Answer: A's one-day work=1/10.
Practice Example 2

Apply the same concept to a similar SSC GD question and keep units consistent.

  1. Read the question.
  2. Write the known values.
  3. Choose the correct formula.
  4. Calculate carefully.
  5. Box the final answer.
Practice Example 3

Check your answer using the reverse calculation wherever possible.

  1. Write the required relation.
  2. Substitute the values.
  3. Simplify each step.
  4. Check the result.
  5. Final: The answer follows from the formula above.

2. Together Work

Add individual work rates to find the combined rate.

\[\boxed{Combined\ Rate=1/a+1/b}\]
Solved Example

Question: A 10 days, B 15 days

  1. Identify the given values carefully.
  2. Write the required formula.
  3. Substitute the values step by step.
  4. Simplify the calculation.
  5. Answer: Rate=1/10+1/15=1/6, so together 6 days.
Practice Example 2

Apply the same concept to a similar SSC GD question and keep units consistent.

  1. Read the question.
  2. Write the known values.
  3. Choose the correct formula.
  4. Calculate carefully.
  5. Box the final answer.
Practice Example 3

Check your answer using the reverse calculation wherever possible.

  1. Write the required relation.
  2. Substitute the values.
  3. Simplify each step.
  4. Check the result.
  5. Final: The answer follows from the formula above.

3. Efficiency

Efficiency and time are inversely proportional when the total work is fixed.

\[\boxed{Efficiency\ Ratio=Time\ Inverse\ Ratio}\]
Solved Example

Question: A takes 10 days, B takes 20 days

  1. Identify the given values carefully.
  2. Write the required formula.
  3. Substitute the values step by step.
  4. Simplify the calculation.
  5. Answer: Efficiency A:B=20:10=2:1.
Practice Example 2

Apply the same concept to a similar SSC GD question and keep units consistent.

  1. Read the question.
  2. Write the known values.
  3. Choose the correct formula.
  4. Calculate carefully.
  5. Box the final answer.
Practice Example 3

Check your answer using the reverse calculation wherever possible.

  1. Write the required relation.
  2. Substitute the values.
  3. Simplify each step.
  4. Check the result.
  5. Final: The answer follows from the formula above.

4. Men and Days

For equal work, men×days remains constant when efficiency is same.

\[\boxed{M_1D_1=M_2D_2}\]
Solved Example

Question: 12 men finish in 15 days; 20 men?

  1. Identify the given values carefully.
  2. Write the required formula.
  3. Substitute the values step by step.
  4. Simplify the calculation.
  5. Answer: D=12×15/20=9 days.
Practice Example 2

Apply the same concept to a similar SSC GD question and keep units consistent.

  1. Read the question.
  2. Write the known values.
  3. Choose the correct formula.
  4. Calculate carefully.
  5. Box the final answer.
Practice Example 3

Check your answer using the reverse calculation wherever possible.

  1. Write the required relation.
  2. Substitute the values.
  3. Simplify each step.
  4. Check the result.
  5. Final: The answer follows from the formula above.
