162 - 52 ÷ 26 + 15 x 5
= 162 - 2 + 75 = 235
40 + 12 ÷ 3 x 6 - 60
= 40 + 4 x 6 - 60
= 40 + 24 - 60
= 64 - 60 = 4
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.
2 x 4 - 3 + 4
8 - 3 + 4
= 9
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.
Statement
U > A = I ? O < E
Conclusions
I. I ? E (false)
II. O > U (false)
Hence, neither Conclusion I nor II is definitely true.
If neither conclusion I nor II follows
K ? D ...(i) D > L ...(ii) L < J ...(iii)
From (i) and (ii) K ? D > L or K > L ....(iv)
Hence I follows
However, From (iii) and (iv) J and H can't be compared . Hence II does not follow.
T ? J ...(i) J ? I ...(ii) I < W ...(iii)
From (ii) and (iii) J and W can't be compared. Hence I does not follow
From (i) and (ii) T and I can't be compared. Hence II does not follow
E < U ...(i) U = R ...(ii) R > F ...(iii)
From (i) and (ii) E < R ...(iv)
Now, From (iii) and (iv) E and F can't be compared
Hence neither I nor II follows.
P < W ...(i) W ? D ...(ii) D > J ...(iii)
From (ii) and (iii) W ? D > J or J < W ...(iv)
Hence II follows. However, from (i) and (iv) we can conclude that J and P can't be compared. Hence I does not follow.
