If a and b represent positive single digits in the correctly worked computation above, what is the value of a + 2b ?  Options:
A) 2
B) 7
C) 9
D) 11
E) 12
Adding the digits in unit's place , 5+ 6 + b = 16 (Since a and b are positive single digits )   =&gt; b = 5   Now adding the digits in ten's place , 5+a + 2 + 1= 9 (1 has been carried over from unit's place addition)   =&gt; a= 1   a+2b = 1+2*5=
