If "-" stands for division, "+" stands for multiplication, "÷" stands for subtraction and "×" stands for addition, (A) : $$8 + 6 - 3 div 4 imes 6 = 16$$ $$equiv8 imes6div3-4+6=16$$ L.H.S. $$=frac{48}{3}+2=16+2=18
eq$$ R.H.S. (B) : $$16 - 4 + 4 div 2 imes 6 = 20$$ $$equiv16div4 imes4-2+6=20$$ L.H.S. $$=(4 imes4)+4=16+4=20=$$ R.H.S. => Ans - (B)
