If 'L + M' means L is smaller than
M. 'L * M' means L is smaller than equal to
M. 'L > M' means L is neither greater nor smaller to
M. 'L @ M' means L is greater than
M. 'L $ M' means L is greater than equal to
M. Which among the following symbols should replace the question mark [?] (in the same order from left to right) in the given expression in order to make both the expressions 'E > K' and 'D > O' definitely true? I @ K [?] J + D [?] E [?] F > G [?] N > O

Given expression: 'I @ K [?] J + D [?] E [?] F > G [?] N > O'. Replacing codes with the symbols, we get: 'I > K [?] J < D [?] E [?] F = G [?] N = O'. 1) I > K = J < D < E > F = G ≥ N = O. It doesn't satisfy the given condition. 2) I > K ≥ J < D ≤ E < F = G > N = O. It doesn't satisfy the given condition. 3) I > K = J < D > E = F = G < N = O. It doesn't satisfy the given condition. 4) I > K < J < D ≤ E = F = G < N = O. It doesn't satisfy the given condition. 5) I > K < J < D = E ≥ F = G > N = O. It satisfies the given condition.
