As 32 = 2^5, for calculating the remainder of 634 digits divided by 32 you need to check the remainder for the last 5 digits only, as explained at the start of the video. Sir is explaining how to determine the last 5 digits out of the 634 and then find the remainder and hence the answer. Watch the video again, it might make sense now :)

Why are we dividing N/32 in last question

that's the question, to find remainder when N is divided by 32.

@aditisrivastavaas3177

Would you plz explain last question fully??

@brijeshshetty7448

4 жыл бұрын

You need to find Remainder of N/32, where N is given as 12345...634 digits which means N contains 634 digits, You know the divisibility rule for 2^n, so even if you find remainder for just the last 5 digits of N, that will give you the answer. Now, 1 to 9 contains 9 digits obviously, 10 to 99 contains 180 digits (90 numbers having 2 digits each). So, 9+180 = 189 digits. You are left with 634-189 = 445 digits. Since all numbers after 99 contain 3 digits, you make groups of 3, that is you divide 445 by 3, that gives you 148 + 1 extra digit. Now, you add 148 to 99, that gives you 247. Remember you have 1 extra digit, so you use only the 2 from next number (248) So your number becomes 2472 That is 4 digits, you want 5 digits so you take only last digit of the previous number that is 6 from 246. Finally, you get last 5 digits of N that you were looking for, that is 62472. Now just divide by 32 as your question demands and there's your answer 8. Just to help visualize, the last few digits of N are like ...2422432442452462472 We only needed last 5 digits in this question to find Remainder.

In the last question 1,2,3----9 there are 9 digits total and then 10,11,12----99 how it can be 180 digits???? Infact from 10 to 90 there are only 80 digits...

@P.verma0

Till the 99 , we already used digits 180+9= 189 Thus we left with only 634-189=445 digits Now how many 3 digits number can we made since we have left 445 digits, So it will we =445/3 Since 445 is not completely divisible by 3, The quotient is 148 and the remainder is 1, So we can make 148 , 3 digits number and one left single digit Then 100,101,.....247 (total 148) If we continue above series 101,102,103,...247248, we can't take the last 48 other wise the number of digits will be 636 Thus the last 7 digits are 2462472 The last 5 digits are 62472
