In the following questions, select the related word/letters/number from the given alternatives.
If we assign numbers to the alphabets such as A = 1 , B = 2 , C = 3 and so on, we get :
$$\sqrt{AFI}=\sqrt{1+6+9}=\sqrt{16}=4=1+3\equiv13=M$$
and $$\sqrt{ADD}=\sqrt{1+4+4}=\sqrt{9}=3=1+2\equiv12=L$$
Similarly, $$\sqrt{ABA}=\sqrt{1+2+1}=\sqrt{4}=2=1+1\equiv11=K$$
=> Ans - (D)
