(ii) No box is at either end of the row.
(iii) Box X is kept to the immediate right of file M, while file O is kept to the immediate left of box Z.
What is kept at the extreme left of the row on the table?​

Answer 1

Answer:

Explanation:

X --- Y ---- Z ---- W ----- M ----- N ----- O

They are kept in an order. (Left to right $\longrightarrow$ )

Conditions and Solutions :-

• Let file O's adjacent have "S" materials. Then, "something" --- O --- "something" will have the same amount of material, ie "S".
• X, Y, Z, W aren't at the corners

A hint! [Neither O is at the corner, so, M and N are (but we need to check the order of placement)]

• Box X is to immediate right of M, O is at immediate left of box Z.

Something like this:-

M ---- X and O ---- Z

Now, the sequences are :-

M ---- X --- Y ----- O ---- Z --- N

• Now, it was said that O's left and right have same amount of materials, and Y and Z are same, boxes.
• M was at left of X, and another condition stated that M and N were at the corners.

Hence, N is at the extreme left of the sequence $.$
