In an Exhibition seven cars of different companies - Cadillac, Ambassador,…

Concept: A linear arrangement puzzle is solved by converting each relative clue -- "nth to the right/left", "next to", "between" -- into position numbers along a 1-to-7 line. Anchor the line first from whichever clue fixes an absolute position (such as "is at one end"), then derive every other position by simple addition or subtraction from that anchor.

Applying this here:

1. Fiat is third to the left of Ambassador and is stated to be at one end; since Fiat sits to the left of Ambassador, that end must be the left end, so Fiat takes position 1.

2. Since Fiat (position 1) is third to the left of Ambassador, Ambassador sits at position 1 + 3 = 4.

3. Fargo is fourth to the right of Fiat, so Fargo sits at position 1 + 4 = 5.

4. Cadillac is next to the right of Fargo (position 5), so Cadillac takes position 6.

5. The three remaining positions -- 2, 3, and 7 -- belong to Bedford, Maruti, and Mercedes. Maruti sits between Ambassador (4) and Bedford, so Maruti must occupy the position adjacent to Ambassador on the still-empty side, position 3, with Bedford immediately next to it at position 2.

6. The last open position, 7, goes to Mercedes.

Cross-check:

• Cadillac (6) is next to the right of Fargo (5) -- clue A holds.

• Fargo (5) is fourth to the right of Fiat (1): 5 - 1 = 4 -- clue B holds.

• Maruti (3) sits between Ambassador (4) and Bedford (2) -- clue C holds.

• Fiat (1) is third to the left of Ambassador (4): 4 - 1 = 3, and position 1 is indeed an end -- clue D holds.

The full row, left to right, is Fiat, Bedford, Maruti, Ambassador, Fargo, Cadillac, Mercedes. The three cars to the right of Ambassador are therefore Fargo, Cadillac, and Mercedes.
