Tailored for SSC MTS Quantitative Aptitude. 1 active practice questions. Related topics: Percentage, Profit and Loss, Simple Interest.
SSC MTS approach: For SSC MTS, build this topic around the core rule and a repeatable direct method. The goal is to reduce hesitation and make basic decisions quickly and correctly.
What to master: Master straightforward forms thoroughly, then add only small variations. Repeated short drills are more useful here than complicated mixed sets too early.
SSC MTS focus:
Master the core rule for SSC MTS and convert it into quick, low-error solving for straightforward objective questions.
Attempt strategy: For SSC MTS, lock the basic rule first, solve with the most direct method, and use short repeated drills to improve speed without adding complexity.
Revision path: MTS revision: basic concept -> direct example -> repeated short drill -> final recall.
SSC MTS exam emphasis for Pipes and Cisterns
MTS emphasis: core concepts, direct solving, repetition, and low-error execution.
Most important error to avoid
Typical MTS loss comes from weak recall of the basic rule, sign or reading errors, or adding unnecessary complexity to an otherwise direct question.
SSC MTS Pipes and Cisterns — MTS direct-method plan
Anchor the topic in the basic rule and a direct solving sequence. Avoid complexity unless the question genuinely requires it. For Pipes and Cisterns, concentrate on work-rate conversion, inlet and outlet direction, combined filling or emptying, and time-to-complete relationships.
How to practise this topic
Practise compact sets where each question reinforces one clear operation, grammar cue, visual transformation, or decision rule before moving to mixed practice. A reliable drill sequence is to convert each pipe to a one-minute rate, combine signed rates, solve the required time, then verify whether the tank should be filling or emptying.
Mistakes to remove before the next set
Watch specifically for mixing filling and emptying signs, combining times directly instead of rates, and missing the net-rate direction. During review, restate the rule in plain language, correct the exact step that failed, and repeat one near-identical example followed by one slightly changed example.

Exam Tips
How to score with this topic
- Read the exact requirement before choosing a shortcut.
- Keep units, signs and percentage bases consistent.
- Use the final few seconds to verify direction and magnitude.
Mistakes
Common traps to avoid
- Using a memorised shortcut without checking its condition.
- Skipping unit or base conversion.
- Doing long arithmetic before identifying the underlying relation.
Solved Example
Step-by-step example
SSC MTS practice example: Two pipes fill a tank in 12 hours and 18 hours. Together their rate is 1/12 + 1/18 = 5/36, so they fill the tank in 36/5 = 7.2 hours.
Practice Preview
Before you solve
- One pipe fills a tank in 12 hours and another in 18 hours. How long will they take together?
Learn the shortcut first
Shortcut before you solve
Pipes and cisterns uses time-and-work rate logic with outlet rates subtracted.
Featured shortcut
Convert each pipe into a one-hour rate; filling is positive and emptying is negative.
Exam-use rule
Net rate = total inlet rate - total outlet rate.
Use this in 3 seconds
Convert every completion time into an hourly rate first.
Faster solving steps
Use this 4-step method before solving to keep your thinking fast and repeatable.
Step 1
Identify relation
Spot the pattern, relationship, or core idea first.
Step 2
Apply same pattern
Use the same rule instead of re-solving from scratch.
Step 3
Eliminate wrong options
Remove confusing choices before comparing the last few.
Step 4
Confirm final answer
Pick the option that matches the shortcut most cleanly.

Convert each pipe into a one-hour rate; filling is positive and emptying is negative.
Tip: A pipe filling a tank in 6 hours fills 1/6 of it per hour.
Real exam shortcut before you solve
A pipe fills a tank in 6 hours. What fraction does it fill in 1 hour?
Step 1
Take the full tank as 1.
Step 2
One-hour filling rate = 1/6.
Rule
Net rate = total inlet rate - total outlet rate.
3-second trick
Convert every completion time into an hourly rate first.
Trap to avoid
Do not add filling times directly.
Correct answer
1/6
Worked example
A pipe fills a tank in 6 hours. What fraction does it fill in 1 hour?
Thinking path
- The full tank is one unit.
- Six hours means one-sixth per hour.
- Multiple pipes must be combined through rates.
Final answer: 1/6
Why this is fast: Rate form makes inlet and outlet problems straightforward.

Q1
Medium
A pipe fills a tank in 10 hours, while a leak empties it in 15 hours. If both operate together, how long will the empty tank take to fill?
Concept type: Filling and emptying rates
Shortcut used: Convert each pipe into a one-hour rate; filling is positive and emptying is negative.
Quick hint: A pipe filling a tank in 6 hours fills 1/6 of it per hour.
Quick idea: The tank will fill in 30 hours.
