Thread: a, b & c, Mostly a

1. a, b & c, Mostly a

1. <LI>Start with a three-digit number, <font color=red>a</font color=red> . (where the three digits are different from one another.)
<LI>Add the sum of the three digits to the original number <font color=red>a</font color=red>, to get a new number, <font color=blue>b</font color=blue>.
<LI>Add <font color=red>a</font color=red> and <font color=blue>b</font color=blue> together to get a new number, <font color=008080>c</font color=008080>.
<LI>Lastly, the sum of <font color=red>a</font color=red>, <font color=blue>b</font color=blue> and <font color=008080>c</font color=008080> is 2070.
What was the original three-digit number, <font color=red>a</font color=red>?

<span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">513

a=513
sum of digits = 9
b = 513+9 = 522
c = a+b = 513+522 = 1035
a+b+c = 513+522+1035=2070</span hide>

3. That was quick...
