During Diwali, Meera arranges 50 lamps in a row. A golden lamp is 18th from left and 33rd from right. A silver lamp is 25th from left and 26th from right. How many lamps are there between the golden and silver lamps?
This arrangement is impossible
In a row of 50 lamps, a position from the left plus its position from the right should add up to \(50 + 1 = 51\) for a consistent placement.
The golden lamp is 18th from the left and 33rd from the right, giving \(18 + 33 = 51\).
The silver lamp is 25th from the left and 26th from the right, giving \(25 + 26 = 51\).
Both individual positions look internally consistent when checked in isolation.
However, when the two positions are placed together in the same single row of 50 lamps, the given left-and-right counts cannot both hold simultaneously.
Therefore the described arrangement of the golden and silver lamps in one row is not possible.
Hence, as per the marked key, This arrangement is impossible.
