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»

1st string 50 m 75 cm = 50.75 m

2nd string 68 m 68 m 58 cm = 68.58 m

3rd string 121 m 3 cm= 121.03 m

On joining three total length = 240.36 m

Now, one string = 240.36 m

Dividing 12 parts = 240.36/12 = 20.3 m.
