sir in Q2 a go 2 day before completetion of work so we have to subtract a work i.e 4 unit from total 20-4=16 so a and b work for 16/3 day + 2 day of b alone then answer will be 22/3......

[@sunnysandy8339]

Bhai iska answer 32/3 days hoga.. itna big mistake ye channel wale kaise kr skte h

[@SwetaKumari-gh4hr]

ye glt bta h rhe kuch kuch questions

[@Mohitbisht1587]

🤣🤣🤣 bhai kya ho gaya ha A chala gaya chorkr...aur last 2 din mai B ko akele kaam Krna pada ha ..B ek din mai 1 unit krta ha to last 2 din mai total 2 unit krega mtlb total work mai se 2 less...18 unit bacha ha jo A aur B ne sath kiya hoga..sath unhone 3 unit kiya ha to total 6 din sath aur 2 din b ke akele ke...8 days...bilkul sahi ha

[@divyanshubhandari5627]

Q)2 is absolutely right ans.Your mind is gobar.

[@narrouttamdas2972]

Sir question no2. As A has leave the job before completion of 2 days. Toh remaining work B 2 main complete krega ye to koi fixation nhi h. Soo I think pehle hme A+B kitna din m job complete kre aur uska ans se 2days minus krna chaiye. Plz ans dijiyega. I'm confuse here.....

[@ijjadavivekananda9946]

in question no 4, before 3 days of completion of work 'A' left which means we should calaculate both A and B's work togethor for those 3 days, not B's work alone, to find remaining units of work

[@xyzzzzzzzzhhh]

a left ho gya to together kaise hoga

[@praneshkarroy5562]

ZIndagi bhar se time and work mein dikkat thi. aapne 22+21 minute mein saare doubts clear kar diye hain. Bohot bohot shukriya Sir. Aap Kamal ke teacher hain! :)

[@arjuntamang883]

in question no. 3 . after working for 4 days b left the work. usme 4 din A OR B dono ne work kiya toh total 3 unit 4 din mtlb total 12 unit banai or fir A ne remaining 12 unit 12 din mai banai. . ans 12 days hoga

[@yellowsky889]

10 days

[@gauravanand6136]

Ha bro sahi bola.par ques m ye confusion h ki a and b saath m kaam karna suru Kiya ki nahi

[@utkarshsharma3098]

Its written B worked for 4 days and left. It is nowhere written that both started working together. The language of the question has confused you.

[@meghasingh4997]

even i had the same doubt...but then in question no.2, it's mentioned the word "together", but in Q3, the word is not mentioned, so we take it as B's alone work.

[@thelearninghub16]

[@kamalmeena4230]

sir ur videos are valueable for us.sir plz explain--- a,b,c can complete a work in 15,20 and 24 days respectively. they started together but B left 2 days before and A left 3 days before the completion of work. In how many days the work will be completed?

[@viveknarayan4599]

Sir, if A does work 2unit/day and left 2 days before it means B have to do 4 unit of work??...in 2nd question

[@inderjeetsingh7770]

You are right but calculation is wrong,2 days are left,a make 2 units b makes 1 unit,total 3 units collectively in one day.2 days are still left and 6 units b had to make.

[@vibhusingh4196]

@7:31 i think there is a mistake. you subtracted only one day work of A in place of 2 days work of A

[@inderjeetsingh7770]

You are right,q no 2.collectively they work 3 units daily ,a left 2 days before,remaining work is 3 units into 2 days that is 6 units.b is making 1 unit daily so remaining work will take 6 days.

[@subhadipchakraborty1968]

Sir my question to God is why i not found you when i was in Class 9 and 10? I always skip dis subject and in Banking Exam i also not try to attempt arithmetic but after seeing your videos i must say why i not found y as a guide when i was in class 9 and 10. I am weak in Math i studied several brilliant Math teacher but nobody broke my fear about arithmetic evry teachers said to me that i am a weak student in math, but finally your videos take me to get out of this fear and now i am quite capable to do Arithmetic. Thank you so much sir.

[@nishantgohil4714]

in question 3, please check it once again. I feel they work together for 4 days

[@rushanshaikh9420]

Same to u.. i also think the same

[@jayantprakash8046]

Thats what sir explained... That TOGETHER word is not mentioned in the question... Therefore, B started the work alone and worked for 4 days.

[@chanchalpapalkar3445]

Sir, your videos are really very much helpful. Your way of explaining is very different and too good. I had watched your 70% vedios and it helped me a lot in clearing my concept. Sir you are just awesome.

[@rkbr3852]

Sir I think questions no. 2 is wrong. Because you takes B (leave the work) in place of A( leave the work) . Please check again. Eska Answers 32/3 hoga. I am sure.

[@vkkushwaha16]

no bro its right.in question A(leave the work before two days )

[@dazzlingnisha2085]

Complicated problems....Easy solution..but because of you only...thankyou for making it very easy

[@thekiller8863]

In Q no 3 why u haven't include A's work u have just subtracted only B's work from total work...what make us know that only B has worked for 4 day and A had not done any work in the period of 4 days of work

[@TA-xg2kw]

The Killer sme query yr I think 1 day work of A+B should be multiplied with 4 I.e. 3 *4= 12 isse bhi 16 answer aaega

[@manishrawat54]

The Killer because in this question they have not mentioned that A and B together started the work, there is no surety of that. And that is why we have considered only B's work for 1st four days.

[@ankitkumar5871]

bro they didn't mention dat they r together so we took it as a part of only B

[@akshayshukla4743]

sir, at 7:20 in the video, we consider B will have to work for 2 more days, hence total work done together by A and B = 18 units. Another way to look at the question - A worked for 2 fewer days. So 4 units of work is something A left. So total work done together by A and B = 16 units. I want to know why is my approach wrong .

[@sangeetashahwal5791]

thanks sir

[@onlineteacher9171]

,In Question 2,your logic is wrong, (A+B) milke 20/3 days mein work complete karta but 2 days before A leaves, so (A+B) together 14/3 days work kiye, in 14/3 days mein jitna work hua vo nikaalenge aur remaining work bhi nikalege, remaining work ko B jitna days mein complete karega aur pahle ke 14/3 days ye dono add ho jaenge aur tab answer aayega, by the way answer (12+2/3)days aaega. kyunki aap (A+B) together kitne days mein work complete kar lete aap nhi calculate kar rhe , aap ye assume kar rhe ho ki B last 2 days mein work complete kar lega but question mein ye diya 2 Days before A leaves, ye nhi duya hai ki last 2 days B work kar ke complete kar dega...............................if i am wrong anywhere ,please anyone correct me

[@arunmenon9806]

Sir in question 3, are they working for 4 days together and B left right? so 4*3=12 units they have made together. balance 12 units A needs to make alone. A makes 1 unit per day. so A take 12 days to complete the remaining work.

[@shwetapandey3758]

Yes, iska answer wrong h

[@krantikumari7648]

Yes, the answer should be 12.

[@jpsirs_sc4531]

sir , in this video in Example no. 4 , i want to ask a question about that, u said that on condition 2 in which A left the work before 3 days , thats why only B does that work for 3 days but on what base u said that B does that work only for 3 days after leaving A before 3 days of competion of work. It is possibly 4 days remain that after leaving of A before 3 days of completion. On what base u can say that because we dont know how many days to complete the work so , condition of A defines that A left before 3 days of completion of work. i think we need to find the completion work in days for A+B+C which is about 10 days approx. so we can say that A leaves before 3 days of completion of work which is in 10 days so B needs to alone work in remain 3 days which is 12 units. am i right sir ?

[@nupursaha2738]

sir ap bohot hi unda karya kaa rahe hai....jane kitnoka bhala ho raha hai....bohot garv hota hai ye dekh kar

[@ramakantasing9456]

Sir I have a question, plz solve the question. The question is--- A and B together can complete a work in 3 days. They started together but after 2days, B left the work. If the work is completed after 2 more days . B alone could do the work in how many days?

[@way2nishant]

i have a doubt in question 2 ... Let agar A+B dono kaam ker rahe hai to X days me complete kr lenge aur A kaam complete hone ke 2 din pehle he bahar ho jata hai that means A+B jo kaam last ke 2 din me krne vale the vo kaam shirf B krta hai...... to last ke 2 din me 6 unit(agar A & B mil ke krte) kaam bachta hai jisko B akela 6 din me krta hai.... to kaise 2unit kaam bachega B ke liye?
