🚰 PIPES & CISTERNS FROM ZERO | QUANT #13 | COMPLETE MATHS CLASS 🔥 Can two pipes fill a water tank faster than one? What happens when an outlet pipe or leakage starts emptying the tank? 🤔 Welcome to QUANT #13 — Pipes & Cisterns From ZERO (पाइप और टंकी), a detailed, beginner-friendly Quantitative Aptitude lesson by TheStudyKit by Xcelera Consulting. In this video, learn Pipes and Cisterns from absolute basics to competitive-exam level in natural Hinglish, with clear explanations, the LCM efficiency method, important formulas, solved examples and exam-oriented shortcuts. 📚 WHAT YOU WILL LEARN IN THIS VIDEO ✅ Meaning of Pipes & Cisterns ✅ Inlet Pipes vs Outlet Pipes ✅ Connection with Time & Work ✅ One Pipe Filling a Tank ✅ Two Pipes Working Together ✅ LCM Method for Fast Calculations ✅ Filling and Emptying Pipes Together ✅ Three Pipes Operating Simultaneously ✅ Pipes Opened or Closed Midway ✅ Finding an Unknown Pipe’s Time ✅ Leakage Problems ✅ Partially Filled Tanks ✅ Pipes Working Alternately ✅ Efficiency-Based Shortcuts ✅ Common Mistakes in Competitive Exams ✅ Solved Questions and Practice Exercises 🧮 IMPORTANT PIPES & CISTERNS FORMULAS 📌 Work Done in One Hour = 1 ÷ Total Time 📌 Inlet Pipe = Positive Work (+) 📌 Outlet Pipe = Negative Work (−) 📌 Combined Work Rate = Sum of Individual Work Rates 📌 Net Work Rate = Filling Rate − Emptying Rate 📌 Time = Tank Capacity ÷ Net Efficiency 📌 LCM Method = Assume Tank Capacity as the LCM of Individual Completion Times 🔥 QUICK EXAMPLE Pipe A fills a tank in 12 hours. Pipe B fills the same tank in 18 hours. How long will they take together? Step 1: LCM of 12 and 18 = 36 units Step 2: Efficiency of A = 36 ÷ 12 = 3 units/hour Step 3: Efficiency of B = 36 ÷ 18 = 2 units/hour Step 4: Combined Efficiency = 3 + 2 = 5 units/hour Step 5: Time = 36 ÷ 5 = 7.2 hours ✅ CORRECT ANSWER = 7 HOURS 12 MINUTES Learn how to solve such questions quickly without complicated calculations! 🎯 WHO SHOULD WATCH THIS VIDEO? 🏦 SBI PO and SBI Clerk Aspirants 🏦 IBPS PO and IBPS Clerk Aspirants 🏦 IBPS RRB and RBI Assistant Aspirants 📝 SSC CGL and SSC CHSL Aspirants 🚆 Railway NTPC and RRB Aspirants 📚 Insurance AO and Assistant Aspirants 🎯 Other Government Competitive-Exam Aspirants 🧠 Beginners and Students Weak in Mathematics 📖 THESTUDYKIT — QUANTITATIVE APTITUDE FROM ZERO SERIES QUANT #01 — Numbers From ZERO QUANT #02 — Four Basic Operations QUANT #03 — Mental Maths From ZERO QUANT #04 — Percentages From ZERO QUANT #05 — Ratio & Proportion From ZERO QUANT #06 — Averages From ZERO QUANT #07 — Profit & Loss From ZERO QUANT #08 — Simple & Compound Interest From ZERO QUANT #09 — Time & Work From ZERO QUANT #10 — Time, Speed & Distance From ZERO QUANT #11 — Problems on Trains From ZERO QUANT #12 — Boats & Streams From ZERO QUANT #13 — Pipes & Cisterns From ZERO 🎓 ABOUT THESTUDYKIT TheStudyKit by Xcelera Consulting is an educational initiative focused on making Mathematics, Quantitative Aptitude, Reasoning, English, Banking and Competitive-Exam preparation accessible to learners.
