Suppose there is a number 235 such that sum of first two digits is equal to the third digit. How many such 3 digits numbers are possible?  Choose one:
A) 42	B) 43	C) 44	D) 45	E) 46
As we know that total digits are   0 ,1, 2, 3,4,5,6,7,8,9   if three digit no is xyz   this means x+y=z must hold   so we have to select two no out of 10   ans is 10 c 2=45   ANSWER:45
<result>D</result>
