• The problem is written like:
  XCL
  ZCB
  ------------------------------
  LZXP
  SZRR
  CCZB
  -------------------
  ZDKBKP
  Here we can see that (Final answer's left most digit that is Z. It depends upon C. Obviously C is added to a carry 1.(The carry after adding two digits will always be 1. Adding 3 digits may give carry either 1 or 2)).
  So obviously C+1=Z i.e {c,z}={{1,2},{2,3},{3,4},{4,5},{5,6}.{6,7},{7,8},{8,9}}(note: c can't be 0 so z can't be 1.)
  Now hit and take trial and observe CCZB must satisfied. U'll see that c=7 and z=8. Now put all the values obtained all across and use your brain. You'll get like this:
  
  9 7 3
  X C L
  8 7 4
  Z C B

  Take the one with most repeating variables. I will take case 2
  XCL
  C
  _______
  SZRR
  _______
  
  start with R=1, take its caes like 3*7 and 7*3 and so on.
  I found 7*3 working, after trying 3*7
  
  this way got the values, after that with minimum trials.
  
  values-
  973

• Go for the second product line, i.e. XCL*C=SZRR.
  So basically you have to think about CL*C such combination which returns the same product value in unit digits (i.e. RR)
  While trying, you will get combinations for CL*C like (37*3), (73*7), (47*4) etc.
  so (73*7) fits proper.
  Hence
  answer is 973

  First hit and trial with value of R
  Take R=1

• C*C=R and C*L=R. If C=7 and L=3 then R=1. And Z is 1 more then C so Z is 8. 8*X should give 77, which is only possible when X=9 and Z*C gives a carry of 5. Therefore, Z is 8, C 7, X 9, B 4, D 5, L is 3, S is 6 and K is 0. Hence 973*874=850402
