What will come in place of question mark (?) in the given equation?
9 ? 11 ? 6 ? 3 ? 9 = 117
Expression : 9 ? 11 ? 6 ? 3 ? 9 = 117
(A) : +, -, ÷ and x
$$\equiv9+11-6\div3\times9=117$$
L.H.S. = $$20-(2\times9)=20-18=2\neq$$ R.H.S.
(B) : x, +, ÷ and x
$$\equiv9\times11+6\div3\times9=117$$
L.H.S. = $$99+(2\times9)=99+18=117=$$ R.H.S.
=> Ans - (B)
