In the following question, correct the equation by interchanging two signs.
6 + 8 ÷ 4 - 4 = 8
Expression : 6 + 8 ÷ 4 - 4 = 8
By interchanging :
(A) : ÷ and =
=> $$6+8=4-4\div8$$
L.H.S = $$14\neq$$ R.H.S. = $$3.5$$
(B) : ÷ and +
L.H.S. = $$6\div8+4-4$$
= $$3\div4=0.75\neq$$ R.H.S.
(C) : ÷ and -
L.H.S. = $$6+8-4\div4$$
= $$14-1=13\neq$$ R.H.S.
(D) : + and -
L.H.S. = $$6-8\div4+4$$
= $$6-2+4=8=$$ R.H.S.
=> Ans - (D)
