Statement
L = M ≥ N;
M > P;
L < K ;
On combing both the statements, we get
P < L = M ≥ N < k
Conclusions
I. K > P (false)
II. N < K (true)Correct Option: B
Statement
L = M ≥ N;
M > P;
L < K ;
On combing both the statements, we get
P < L = M ≥ N < k
Conclusions
I. K > P (false)
II. N < K (true)
Hence, only Conclusions II is definitely true.

The given expression is 42*4*12*9 = 0
From option (c), 42,  4 ÷ 12 x 20 + 9
By coding, the equation becomes,
LHS ⇒ 42 x 4 + 12 ÷ 20  9
By applying the operations in sequence, from left to right,
168 + 12 ÷ 20  9
180 ÷ 20  9
9  9 = 0 = R.H.S.Correct Option: C

40 + 12 ÷ 3 x 6  60
= 40 + 4 x 6  60
= 40 + 24  60
= 64  60 = 4Correct Option: D
40 + 12 ÷ 3 x 6  60
= 40 + 4 x 6  60
= 40 + 24  60
= 64  60 = 4
