Which of the following symbols should be placed in the blank spaces respectively (in the same order from left to right) in order to complete the given expression T_D_S_A_W_R_U in such a manner that ‘W not greater than equal to T’ definitely holds true while ‘ U < A ’ definitely holds false?
‘W not greater than equals to T’ means we need ‘W < T’ to be definitely true. And for ‘U < A’ to be definitely false we need any of U > A, U ≥ A or U = A to be definitely true. Hence by option 4, T ≥ D > S ≥ A = W ≤ R ≤ U We get ‘W < T’ and U ≥ A. so option 4 satisfies the given statement.
