Question

Three strings of lengths 50 m 75 cm, 68 m 58 cm and 121 m 3 cm, respectively, are joined together to get a single string of greatest length, and the length of the single string obtained. If this single string is then divided into 12 equal pieces, find the length of each piece.

Answer 1

Given

First string 50m 75 cm = 50.75 m

Second string 68 m 58 cm = 68.58 m

Third string 121 m 3 cm = 121.03 m

On joining the length of three strings = 50.75 + 68.58 + 121.03

= 240.36 m

Now,

One string = 240.36 m

Dividing the strings into 12 parts = 240.36 / 12

= 20.03 m

Therefore, the length of each piece is 20.03 m
