Hi,
Note: Let td represent a 2 digit number. Then (10*t + d) is the value of the number.
.
Write as You Read
(10*t + d) = 4(t + d)
.
simplifying
10*t + d = 4t + 4d
6*t = 3*d
.
If t=1, then d=2  for example
12 is exactly 4 times the sum of its digits 4(1+2) = 12
.
If t=2, then d=4  for example
24 is exactly 4 times the sum of its digits    4(2 + 4)= 24
.
If t=3, then d=6  for example
36 is exactly 4 times the sum of its digits    4(3 + 6)= 36
.
If t=4, then d=8  for example
48 is exactly 4 times the sum of its digits    4(4 + 8)= 48</PRE>
