If a and b represent positive single digits in the correctly worked computation above, what is the value of a + 2b ?  Choose the most appropriate option.
A) 2	B) 7	C) 9	D) 11	E) 14
Adding the digits in unit's place , 2+ 2 + b = 10 (Since a and b are positive single digits )   =&gt; b = 6   Now adding the digits in ten's place , 2+a + 3 + 1= 8 (1 has been carried over from unit's place addition)   =&gt; a= 2   a +2=
