If 201 digits were used to number the pages of a book, starting from 1, find the number of pages in the book.
Do pls share your logic friends
The capital of a company, Estyle, is made of 75,000 preferred shares with a dividend of 15% and 20,000 common shares, with the par value of each type of share as Rs 10. The total profit of Estyle was Rs 2,40,000 of which Rs. 40,000 was kept in a reserve fund. The remaining profit was distributed to the shareholders. What would be the difference in the dividend percentage given to the common shareholders if the amount kept away in the reserve fund was reduced to Rs 25,000?

FRACTIONAL PART AND INTEGRAL PART
R=(5*rt5+11)^2n+1 find fractional part of this number .
let f is fractional part of this f=R-[R]
let a number X=(5*rt5-11)^2n+1
X will lie in 0
so R-X=2*(2n+1c1*(5*rt5)^2n*11+2n+1c3*(5rt5)^2n-2* (11)^3......
so R-X=even number
so f-X=an integer (odd or even both possible)
so fractional part is (5rt5-11)^2n+1
so f=1-x so 1-(5-2rt6)^n________________________
Note - 1) in R=(a+b*rtc)^kif k is odd then f=X
fractional part will be f=(a-b*rtc)^n
2) and if k is even then f+X=1
example )find greatest integer less than or equal to (rt2+1)^6
ANS- here n=6 means even
so f+X =1 so
so (rt2+1)^6 =integer+fraction
Now solve (rt2+1)^6+(rt2-1)^6 by simple binomial expansion

Guys what is the solution to the generalized eqn a/x+b/y = c/n ??
Karan wanted to go to a Sonu Nigam concert at Ambala. Unfortunately, he could not get a ticket because the concert was sold out. He located a tout who was willing to sell him a ticket at a premium. The tout begins by asking Rs. 1000 for the ticket. Karan countered by offering Rs. 500. The tout, knowing that Karan was a Bulls Eye Math faculty, always countered by asking Karan to pay the average of the two offers. Karan countered by always asking the average of his previous offer and the tout's new offer. At what price did Karan finally buy the ticket? (rounded to the nearest Rupee) 667 888 725 NOTA
Does anybody have the Totdal Gadha PDF on PNC and Probability
