Given,
A piece of wire is cut into two parts in the ratio 2 : 3 and the length of the longer piece is 81 cm.
To Find,
The length of the shorter piece.
Solution,
The 2 parts of the wire are in the ratio 2:3.
Length of the longer piece = 81 cm.
Taking the ratios as 2x and 3x,
Given → 3x = 81.
Therefore, x = 81/3 = 27.
Length of the shorter piece = 2x = 2 x 27 = 54 cm.
Therefore the length of the shorter piece of wire is 54 cm.
