In the simple subtraction problem below, some single digits (not necessarily distinct) are replaced by letters. Find the value of 2*A + 2*B + 4*C*D.
A9C5
- 2B79
--------------
633D

a) 50
b) 52
c) 66
d) 48

• A9C5
  -2B79
  ----------
  6336 since,15-9=6. from there,D=6 and solving all,we get A=8,B=5,C=1.
  So 2*8+2*5+4*1*6=50

• A9C5
  -2B79
  .................
  6336
  so
  A=8
  B=5
  C=1,and
  D=6
  
  so
  2A+2B+4CD=2*8+2*5+4*1*6=50
  so option a is correct.

• D=6
  C=1
  B=5
  A=7
  2*7+2*5+4*1*6=48

  ---------
  633D
  NOW, D=6 as 15-9=6, and c-(7+1)=3, c=11 i.e value of c in the expression is 1, and b=5 as 9-(b+1)=3, and A=8 as A-2=6
  so 2*A +2*B +4*C*D=16+10+24=50

• A=8,B=5,C=1,D=6
  SO, ANS= 50
