In the following question, by using which mathematical operators will the expression become correct?
30 ? 6 ? 4 ? 5 ? 4
Expression :Â 30 ? 6 ? 4 ? 5 ? 4
(A) : $$30+6=4\times5-4$$
L.H.S. = $$36$$
R.H.S. = $$20-4=16\neq$$ L.H.S.
(B) : $$30-6=4\times5+4$$
L.H.S. = $$24$$
R.H.S. = $$20+4=24=$$ L.H.S.
=> Ans - (B)
