L:G= Ratio between Lax. and Gop. = 3:4
L:L'=Ratio individual salary of Lax. = 4:5
G:G'=Ratio individual salary of Gop.= 2:3
Now, L:G = 3x:4x [Meaning L=3x and G=4x]
Put this in L:L' and G:G' we get
3x=4/5 and 4x=2/3
meaning we get value of each unit of salaries of Lax. and Gop. as
1= 15x/4 and 1=6x
Since addition of their salaries is 4290. So,
15x/4 + 6x = 4290
By solving we get
x=440
Now put this in the value we got of their 1 unit
So
Lax. = 15(440)/4= 1650 and
Gop = 6(440)= 2640
awesome sir..uh made it so easy..Jo class me nai samjh sakte vo yaha clear ho jata h..thank uhh very much..
we are lucky to have a teacher as wonderful as you are.Wishing you a very happy teachers day.i'm learning lots of thing from your channel.thanks for all kindness & love towards us.
Sir jb b apki vedios dekho bs esa lgta h ki wahoo yr kya teacher haii ...❤ek ek cheez ache se smjh aati hai..apke jesa na kisi ne padaya h na kabhi vo ptani..pr sch m hats off to u ki apne etni mehnat se yeh bnae h or sare concept qs cover kiye hai thank you so much sir
it's mid-2020 and still lectures are unbeatable
Basic se clear ho jata hai sir aapke video se.. You are a legend sir
Sir question 9 m doubt h ...(4:9)=12x kyun kia? Aur L:G =12x:16x kyun kia?
Que.9 1yr ago salary of L:G 3:4 take it as 60:80. Now salary of lxman from last to this year given as 4:5 we can say it is increase of 25% (if you know reciprocal in percentage) same for gopal increase of 50%. Remember 60:80. Increase them 25%:50%. I.e 75:120. Lxman salary is 75/195 *4290 solve this and u get answer
best explanation.....sir...plz make video on LCM and HCF
Thank you sir . This video helps me a lot 🙏😊 muje maths bahot dar lgta tha but ab nhi
I am watching ur video first time really..it's so informative thank you for putting this sort of laudable effort but please go little slow....just add 8 to 10 sec more in each question
I am going to tution for preparation Ssc,Bank But yours teching is very diffeent and very Good and I am imidately understand
+studysmart: Sir., please explain why the number 4 was multiplied in Q.No:9. Many students have raised the same question. Please please explain.
For easy calculation.. sir Had solved question already but he saw that there a fraction us obtained when we do it in normal way without multiply by 4..
Wahi to....i mean aap aise sirf particular question ko hi kr skte ho...smart approach aap har kisi question me kar dete to alag baat thi...exam me value thodi na same ayegi.....
Smart approach se mt jao..sidhe concept ko smjh ke hi krna
He use 4 because 4 is least no when we multiply to both it give that value which do not give any effect to their ratio
The no is depend on value so dont confuse
.
Sir aap bohut achhe se samjhate hain ...koi bhi confusion nehi reheta hain ...❤️ From West Bengal
Sir Q-9 was like mystery....
😆😆😆
Aao kbhi Havelee Pe

Sir actually I hv a friend name chandrakesh from up and his tone 99 percent of ur tone. And from first introduce of ur video I got it that always my friend is stayed with me. Don't mind sir as i for sharing my privacy .
Thanking u sir.....
sir question no. 9 is not understandable, please provide traditional method for this. It will be very nice of you.
By traditional methods, you can't clear any competitive exams.
@@PradeepSinghRajputOfficial true😂
yes
@@PradeepSinghRajputOfficial bro 12x or 16x kese aya???
4/9 = 12x this means 1/9 = 3x (if we devide both sides by 4 or in simple terms cancel out)and here we need to calculate value of 5/9 in terms of x which will be 5 multiplied by 1/9 which will be same as 5*3x or = 15x. Hence the previous salary was 12x and new salary is 15x.
I hope this helps a little bit.
Sir I must say, you are better than other high rated coaching centre's teacher
Thank you sir.This is very help full for us.
Smart methodes are useless but you are great pls explain normal methodes too.😊 Love you a lot
Thank you

Sir., thank you for explaining full concepts...
No one will explain like u sir... Others are explaining just part 1 and part 2 and asking to join online coaching classes but you are not like that... Once again thank you for your videos sir...
Sir I have seen ur all video... Can you please give explain this question....A hound pursues a hare and takes 6 leap for every 9 leaps of the hare, but 3 leaps of the hound are equal to 5 leaps of the hare. Find the speed ratio of hound and hare....???
Plz give me solution...
Its a Case of Ratio Only.
Soln.- Ratio of Hound Hare
Leap Freq. 6 9
Lean Length 3 5
and simply do cross multiply ie. (6x5):(9x3) = 30:27 And U can also solve in simplest form also. I hope U got it.
.
Perfect hai apke padhane ka tarika!!!
A:B=4:5, B:C=3:4, C:D=6:7, A:B:C:D=?
sir ye wala q kaise bnega

Sir ap bohut lucky ho sir samajh aya sir......
For everyone below in comment section who did not understand the need of multiplication by 4 in Q9, you can solve the Q without multiplying by 4 directly. It will give u same answer.
Bht Acha video h sir ....bht ache se smjahaya h aapne
Eg 9 ,why multiplied by 4,only by 4
Sir all the questions was very well explained... Except question no. 9
I did not understand this question no 9 'how you calculate lakshman =12 and Gopal =16 .
3 : 4 ratio ko * 4 karo = 12 : 16
but i too have many doubts in that question.
Sir ap bohot bohot bohot acha math padhate hai sir.thanq

K
सर Balancing of Ratio बताइए मैंने आज क्लास किया बैंकर्स अड्डा में वहां बताया गया वह बहुत सारे मैथ में बहुत अच्छे तरीके से हेल्प कर रहा है बनाने में लंबा-लंबा Math Balancing of Ratioके माध्यम से अच्छी तरह से कम समय में बंन जारजारहे है लेकिन वहां हमें समझने में थोड़ी कठिनाई हुई क्योंकि फास्ट मोड में बताया जा रहा है
बहुत ऐसे प्रश्न होते हैं जिसे हम लोग x मानकर काफी केलकुलेटीभ बना लेते हैं लेकिन बैलेंसइन ऑफ रशिया से इतना आसानी से बन जा रहा है जिसका कोई हिसाब नहीं
I really skip whole ques 9 after 4 is coming😅😂
very good basics also got very much clear...... tnx
No.9 mai app kaise 12x our 16x likha hai yea logically posible nahi hai bataiye
Explain Question no.-9 I got the answer now but it’s difficult to remind until exams or for long time, but if once I understand regular method it’ll be easy to remember.
Questions 9 me 4se hi multiple kou kiya???????
Bcoz he wants to maximize the ratio's i.e. if u will multiply with 3 then ratio becomes 9:12 but if u multiply with 4 then ratio becomes 12:16, however the ratio should not be disturbed...and also more is the number less time is required to cancel at last step...Hope it helps....
Watch the solution in this link , i think the answer was wrong which was explained by study smart

Nambada Naveen looks even more perfect than the process explained in the video. Nice share.

In a mixed juice, the juice of juice 8: 1 was mixed with another mixed juice, in which the apple and orange juice had a ratio of 1:10. If both the mass ratio in the new composite was 5: 1, the ratio of the aperture and oranges in the new blend .
Ans-449:145
sir plz solved this question.
Best ever Maths class witnessed. Mind boggling tricks. Great work.
Thanks Sir.
You are such a genius.....🙄🤘
ques 9)
ratio of laxnan's last year and this year salary is 4x and 5x.
ratio of gopal's last year and this year salary is 2y & 3y.
given that , 4x/2y=3/4
which gives 8x=3y -----------(i)
also 5x+3y=4290 -------------(ii)
solving eq i and ii, we get
x=330.
so laxman's current salary is 5x=5*330=1650
Bahut accha samjhate ho aap sir
Thank you sir
