# Aptitude Video Lessons - Number Systems

Friends, finally we managed to provide you with Video Tutorials in our blog. Here is Gr8AmbitionZ.com's first video lesson on Quantitative Aptitude Basics. Here we have discussed the important concepts of Number Systems. We tried to make it simple so that you can easily understand the concepts. We have covered all the important basics like Divisibility Rules, finding out the unit digit and last two digits of the number, finding out the highest power of the number etc. We hope this will help you in your preparation.

Note : Don't forget to take your homework after the completion of the video aptitude class (check details below).

Check the video below. All the Best and Happy Watching :)

16. Really Nice Video .. Very helpful ..
Thank you So much..

18. Awesome work ..

19. 87^474= (87^2) *(87^4)^118
87^4= XX61 Now how you got 6 as 10s digit (as you multiply 8 and 4 to get 32...so 2 )

20. great ideas.

There is minor mistake in trick to check the Divisibility by 11.

For Ex:

If we take 1069

According to your trick.. last number in 1069 is 9. Double of it is 18 and Truncated number :106

106-18=88 which is divisible by 11. This means that 1069 is divisible by 11

But if divide 1069/11 = 97.2.

1. your inference from the video is wrong.. please check the video again.. the method which you have worked out is not the same as the one thought in the video.

2. actually u r mistaken divisibility of 7 by 11 ...
here ,for divisibility of 11 we substract 1* last digit according to video i.e.,according to ur eg..
if we take 1069..
1069=106-9=97 which is not divisible by 11 ...hence the method shown in video is perfectly alright @Anonymous

22. who will solve this ?
4 7 24 93
2 a b c d e
wot will come for "d"?

23. awesome work and shortcuts... thanks a lot..

24. thank you very much
