Pipes & Cistern Shortcut Tricks | PSC/SSC/RRB Exams

[@Mithilajtn]

answer will be 24 Total Efficiency = LCM of 30, 40, 10 =120 A = 120/30 = 4 B = 120/40 = 3 A+B+C = 120/10 = 12 then C = 4+3-12 = 5 then time = 120/5 = 24

Pipe and cistern itre simple ayrinnnoooooo.......NO EQUATIONS ONLY CONCEPTS...superb......and 24 for last quz.

Lcm= 120litre A+B+C in 10m =120l In 1m =12li A in 1m =120/30=4li B in 1m =120/40=3li A+B+C = 12li 4+3+C= 12li C = 5litre in 1 minute So 120li/5 litre = 24minutes Sir thank you very much. ഇപ്പോഴാണ് ഇതിനെ പറ്റി clear ആയി മനസിലായത്.ഒരിക്കൽ കൂടി നന്ദി

A+B+C lcm 120. So efficiency 12 A efficiency=4 B. =3 Total 7 Then 12-7=5 120/5=24

[@divyadasdivyadas3260]

Total efficiency=10+30+40=120 Efficiency of A=120/30=4 Efficiency of B=120/40=3 A+B+C=120/10=12 Efficiency of C=12-(4+3)=5 time =120/5=24

[@syamasibi518]

Pipe A can fill a tank in 10 h. Pipe B can fill the same tank in 12 h. Pipe C can empty the full tank in 16 h. All the pipes are opened at 8AM and closed at 10AM. Aftet how much time from starting will the tank be empty? Sir.. Plzzzz solve it🙏🙏🙏🙏cheythit kittunnillaa.

[@shameerali1714]

thank you sir,class valare helpful ayi.

[@despatchrider]

LCM of 30 & 40 (capacity of tank as) =120 Time taken to fill the tank when three pipes open =10 min Total efficiency =120/10= 12 Efficiency of A&B =4&3 So, efficiency of C =12 - (4+3)= 5 Time taken by C alone = 120 /5 = 24

[@shanavas8647]

Thank you sir , it is amazing

[@vijeesh66]

good class

[@nikeshjayaraj5267]

LCM of 10, 30, 40 =120. Efficiency of all three taps = 12 Efficiency of Tap A = 4 Efficiency of Tap B = 3 Therefore Tap C = 12-4-3 =5 Therefore time taken = 120/5 = 24 mins.

[@vishnuanilkumar5524]

A+b+c eff = 120÷10=12 C = 12- 7 = 5 unit C time= 120/5 = 24

[@ShyamKumar-eb9ez]

A=30 B=40 A+B+C=10 Lcm=10,30,40 (120) 12-4+3=5 C= 120/5=24 Answer is 24

[@safwankanniyath7694]

30 , 40 , x so lcm taken as x then x/30 , x/40 , x/x adding these three is the togethor so x/(x/30+x/40+1) = 10 therefore 120 x = 70x + 1200 so x = 24

There are 4 pipes that can fill a tank in 20 hours, 30 hrs, 40 hrs,60 hrs respectively. If A opens in 7 am,B opens in 8am, C opens in 9 am and D opens in 10 am. When will the tank fills?????

answer=24 [1/A+B+C]-(1/A +A/B) = 1/C 1/10- (1/30 +1/40 ) = 1/C 1/C = 5/120 C=24 MIN

24 sir. Good class. Thanks.

[@deepthypoulose3638]

I'm able to answer your questions before you explain the sums from second sum. It means that the first sum's explanation was good enough to understand the concept.

[@eveningstar173]

good way to solve these type of maths ❤

[@fantasycricketworld7972]

Last question answer is 24 hrs Step {A+B+C}/10 =A/30 +B/40 + C /X LCM of 10,30 and 40 is 120 so total work will be 120 A+B+C can complete 12 work A can complete 4 work B can complete 3 work So C can compelte remaining 5 work so ans will be 120/5 = 24 hrs
