Re: Types of Numbers  
Hmmmmmmmm, Nice 
Re: Types of Numbers  
Hey just joined your forum....found amazing information from it.....looks very useful..... thanks for such wonderful threads and keep them coming 
Re: Types of Numbers  
Very useful thank you 
Re: Types of Numbers  
hi thanks for such informative articles can i get articles before july 07 also 
solve  
if 21 base n * 36 base n = 776 and 12 base n * 63 base n = x base n solve for x
510 540 776 756

Re: solve  
ans 17. its actually coming out as 16.667. let 'L' be the pizza radius,r be the inner circle radius then, (Lr)sin30'=r.....by geometry thus,r = L/3...hence get the answer 
Re: Types of Numbers  
very useful waiting from long time.... 
Re: software engineer(21 base n * 36 base n = 776 base n)  
oooooooooops can u ans my que. 
Re: Types of Numbers  
it was very nice thanks 
Re: Types of Numbers  
can anyone solve dis prob? Let N= 2^23 * 3^21. How many positive divisors of N^2 are less than N but don`t divide N? 
Re: solve  
Good one... 
Re: solve  
Hi TG, Thanks a ton !!! I got the concept !!! Hats off to u Don't know wat I'd have done without u guys !!! I'm addicted to TG.com now !!! Can u beat tat!!! Thanks. 
Re: Types of Numbers  
gud one.... 
Re: Types of Numbers  
I hav come across various sites/forums for CAT prep but this outperforms all of them. TG rocks ....

hi.......... firstly i thanks for giving such an important concept on number system ,which i don't know previously 
Types of Numbers  
A nice one

Re: solve  
the answer is 776 as 21*36=12*63 
Re: Types of Numbers  
cool one with complete picture on Types of Numbers 
Re: Types of Numbers  
thnx alot for providing such rare information.... 
Re: Types of Numbers  
Hi TG sir, Thanks a lot for such useful information. Can we proceed the exp  5 in a faster way like, (p+q)**2  pq = 30**2 1 = 899. Thanks. 
Re: Types of Numbers  
mind blowing sirjiiiiiiiiiii 
Re: solve  
ans is 776 
Re: Types of Numbers  
Could you please explain the logic behind the following line from your solution....a detailed explanation, if given, would be admired... "factors of N^2 less than N= 1010" 
Re: solve  
Could you please let me know what a perfect number means? 
Re: Types of Numbers  
hi kumar, Let N= 2^23 * 3^21. How many positive divisors of N^2 are less than N but don`t divide N? i am sorry for my ans.its totally absurd 
Re: Types of Numbers  
Hi destiny unruled Slight error. Number of factors of N less than N = 528  1 = 527. So the required answer will be 1010  527 = 483. Kamal Lohia 
Re: Types of Numbers  
Yeah made a mistake. Thank you Sir 
Re: Types of Numbers  
@Rajsekaran: In the Home page of TotalGadha.com, go through KL Math Corner, these concepts have been extensively dealth with....... 
Re: Types of Numbers  
Forgive me for the mistake. The question is to find the last two non zero digits of 50! and 90! 
Re: Types of Numbers  
go through the theory that Kamal has discussed on the following page: http://totalgadha.com/mod/forum/discuss.php?d=8392 its a great article. i am sure you will be able to solve the sums yourself, after reading it
