Gourav Mishra is best in teaching Maths..Class12 maths chapters also would have been taught by GouravMishra

[Maninder_Singh_Charak]

Super method of maths teaching on YouTube. No one can teach as you are teaching sir .(Gurav sir jii)❤❤❤❤

[jaimans]

thank you, sir, best explaination,

I think i am blessed to have tutors like you, thank you so much

and also, at time 7:40:05 the answer of the second try yourself question is: -

Equation for finding 'r' is: - r²-13r+42= 6 or r²-13r+36=0
by splitting the middle term, the values of 'r' are: - r=9 and r=4
here r=9 is not possible
∣⁵P₉ ≠not possible
so, the possible value of r is = 4

I hope it may be Correct,

Thank you.😊😊

Sir, 1:33:35, In example 2 digit no. mai 3 places fill karni h 0, 2, 5, 7 h unity place me 2 digit and, 4 digit aayenga because repetition is allowed so why you fill in 2nd place in 3 digits ?

[KhushbuRani-sthn]

1:33:28
Another way :- 4×4×2=32 .
If we use 0 in hundred place then it will form 2-digit no. And if we use 0 in both hundred and ten place then 1-digit no. will form.
Correct me if I am wrong 👇

[YashSingh-kurg]

Wah sir ji kya padhate h aap mja aa gya😘😘😘😘😘

[sonakshiparida]

Pranam sir
Apki explanation bilkul super se upar
Mera isko request manoge advice kabi nahi
Sir 100 aur 1000 ki bich me
9× 10 ×10=900 number sayed honge
Kyun ki hundred place me 0 ko chhodkar 9 ways baki tens aur unit pace me 10ways rahenge

Can you please explain my doubt. In how many ways can 6 rings of different types be had in 4 fingers. This is in rs aggarwal. Solved example. My doubt is that in first finger all six rings can be worn. Similarly in second finger and so on. So number of ways comes out to be 6 to the power 4. Why is this wrong? In book ans is 4 to the power 6.
