A + B = C
D - C = A
E - B = C
Based on the above equations, can you find out the outcome for:
D + F=?	Options:	A) 15	B) 14	C) 13	D) 12	E) 10
In this question, the alphabets represent their equivalent numeric position.   A = 1, B = 2, C = 3 and so on.   Thus,   A + B = c   =&gt; 1 + 2= 
<gadget id="calculator">1 + 2</gadget>
<output>3</output>
3   D - C= A   =&gt; 4 - 3= 
<gadget id="calculator">4 - 3</gadget>
<output>1</output>
1   E - B= C   =&gt; 5 - 2= 
<gadget id="calculator">5 - 2</gadget>
<output>3</output>
3   Which is why,   D + F= 4 + 6= 
<gadget id="calculator">4 + 6</gadget>
<output>10</output>
10   Since, J is the 10th alphabet,   D + F= J.   correct answer is 10)10
<result>E</result>
A + B = C
D - C = A
E - B = C
Based on the above equations, can you find out the outcome for:
D + F=?
