Are yr... Ye bhaiya simple se math ko kitna long me bata rhe hai. Ex- q no. 2 .... Solution- left work is given by 1-( A's 4 day work+ B's 4 day work) =1-( 4/15+4/20)=1-(7/15) =8/15 worl is left.
LCM of 9,6 should be 18, which is the Total work and then A ka ek din ka kaam 3 hoga(dividing18/6) and B ka ek din ka kaam 2 hoga(dividing 18/9) so total A or B ek din me 5 kaam karenge or total kaam 18 hai, so dono milke 18/5 din me kaam khatam kar denge
Amandeep Singh i never said solution is wrong for this instance but LCM is least common multiple and lCM of 6,9 is 18. The whole idea to comment here is to understand correct approach and correct explanation, rest if you want to follow, its your choice.
@@AmandeepSingh-wd9sj pagal h bhai tu? Kya familiar with method bol ra ans lane k liye kuch bhi thodi na kar dega paper k wakt terko pta hoga 3.6 ans h? Abe paglet h kya lcm galat bol ra wo teacher h itni choti chijj to pta honi chiye
@@krishna9237 Bhai saab agr apne Full pada ho toh tb samj aata mera bolne ka mtlb yei tha ki aapko sabhi methods sei answer nikalna aana chahiya.... baki Jo aapne samjha vo Apne thik samjha. Aur Mera sei bade Pagal toh tum ho Jo bina socha samjha kuch type kr rahe ho....
Sir jinka math acha naa hu our voo Sikh ke chah Kar Lea our answer bhi niklnea lag Jaye to Jo ander se Khushi huti hai Sach Dil khush hu jaata aapke batane se Mera doubt our clear hu Gaya ThAnkuuu sir Mera math bahut kharb tha pahle

I read it a year ago and now i have 9 Lamborghini 7 gf's iphone 12 and many more, but still have one heart one body and one life i only regret about it! No matter ;) Thanks bro m aapke efforts ko kabhi nahi bhul skta thank u so much tumhara ghar abad ho jaye tum bhi mere jese amir ban jao 😐
Sir I am a 8th class student and I did all the questions without seeing the solution . And all were correct. I took max to max 5 minutes for a any questions
LCM(6,9) = 18 = Total work Then, efficiency of A=3 efficiency of B=2, Therefore, Time= Total work/ Total efficiency Time= 18/5 Time=3.6 Days This way is also correct.
everywhere in calculation we can take the LCM of the given numbers which is exactly divisible by these numbers (it's not necessary to take LCM take the number which is exactly divisible by these number )
sir aaj ki class me aapne ek baat khi ki (me smjha ke rhunga ) is baat se bhut jada motiation mila ki agr hum man se jo krna chahe to bilkul kar skte h thanks for such a amazing class sir and thnku wifi team u all r rockstar 👏👏👏👏👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍🙇🙇🙇🙇👌💪🤗🤗🤗
Honorable sir, i am glad to ur teaching technics,,, excellent explanation, i can only say fantastic teaching channel to achieve broad concept With pleasure from jajpur, odisha
A 450 ltr water tank has on outlet C and two inlets - A AND B ( which alone con fill it in 8 hours and T hrs respectively ) when both inlets where opened ( simultaneously) for four hours, 45 ltrs more water was required to fill the tank completely . if C has an outflow rote of 30 ltrs / hours, what is the difference between time taken by B alone to fill the empty tank completely and time taken by C to empty the full tank completely?
Love you lot sir ... You are the best..... Thank you for supporting us... Itna basic se aap ki tarah Koi Nahin samjhata Hai...💖 you doing best job ever
I like the way u taking water after every 20 min nd m also doing in the same way.. Between thank u for teaching us.. 😇 I think is baar clear ho hi jayenga.. Finger cross😓
11. 37.5 12. 18 13. 750 14. 16 days Thank you... i am studying these comepetive math for first time... or aapke 1st lecture ne bahut badhiya smjhaya... great work..
A B and C together can finish a piece of work in 12 days, A and C together work twice as much as B, A and B together work thrice as much as C. In what time (in days) could each do it separately ? Please iska solution de do koi ....same by method taught by Sahil Sir
