  • @jayrathod2172
    @jayrathod2172 3 роки тому +12

    If anyone wants to understand what just happened in 44:30 question no 9.
    suppose, the common remainder is k and HCF is x.
    47 = ax + k
    35 = bx + k
    27 = cx + k
    we cant calculate HCF x of 47, 35, 27 because we don't know the remainder k
    so 47 - 35 = 12 = (a-b)x , 35 - 27 = 8 = (b-c)x , 27 - 47 = -20 = (c-a)x
    and HCF of all this 12, 8 and 20 has HCF x and it is free from remainder k

      But in the question they given
      If (X-4) is HCF to those equations then what is K value?...
      So when we put X= 4 in the both
      equations they must get satisfied..
      That means when X=4 both equations get equal value.
      So putting X=4 in both equations

    The explaination is really wonderful. Me just want a few things. It is not a must to find HCF when greatest is mention. We have to check whether it is written "divided by" or "divides" in the question alongwith. For example, in a question like" find the greatest no of 3 digit which when divided by 6, 9, 12 leaves 3 as remainder in each case". Here we have find the LCM of the nos. and then carry on the other steps as required. Actually I derive it after practicing few problems of HCF and LCM.

    Your method is wrong. Remainder can never be larger than the divisor . Ques 3 , ans is 13 but the last part (93) has remainder as 15. when 93 is divided by 13 remainder is 2 .
    Also in Ques 6, you derived the ans as 1461 , remainder 21 isn't possible in any case as all the divisor are smaller than the remainder. 1461 gives remainder 9,5,3,1 for divisors 12,16,18,20 respectively.

    • @mathsparAptitude
      @mathsparAptitude 5 років тому +2

      A very good observation. In that sense, both the questions (3 and 6) are wrong. Also, the solution for Q15 could have been a little more elegant. The sum of 156, when divided by 13 (the HCF) gives 12. So, essentially, we need two numbers that are co-prime (so that the HCF remains 13) and that add up to 12. The only two pairs that work are 1 and 11 and 6 and 7. This is simpler than having to work with larger 3-digit numbers and checking if their HCF is 13.
      Still, I must add that such mistakes do creep in at times and it should not be allowed to cloud the good work done by CareerRide or other educators.

    For Q3, if you consider a=bq+r, then you have 17=bq1+4, 42=bq2+3, and 93=bq3+15. Clearly, bq1=13. Since 13 is a prime number, q1 must be 1. But b is also the HFC, so the answer is 13.

      @indrayudhpaul6445 Рік тому

      But 93%13=2.
      In the question, it's 15 (which is again 13+2). So I am a bit confused if the question is correct or not.

      If (x-4)=0 then x=4
      Equate both the equations
      then substitute'x= 4' in those equations then we get
      16-32+15=16-4k-1
      -1=15-4k
      4k=15+1
      4k=16

      But when we put 'x=4' in two equations ,
      we get '-1' in both the equations
      -1=-1 .
      To find 'k' we equate both the equations that means both the equations has same value.

      answers should be equal instead of equations equal to '0'.

    15) question
    My solution
    A+B = 156
    HCF = 13 which means A and B both are multiples of 13, so take it common.
    13(A+B) =156
    i.e. (A+B) = 12
    So the pairs are (1,11), (2,10),(3,9),(4,8),(5,7),(6,6)
    Now in these pairs choose only pairs whose HCF is 1
    Therefore answer is (1,11) and (5,7).(2 pairs)
    Ps: I found this easier 😂...I don't like big numbers
