Question

The ratio between 3 different electric wires are 3:2:7.if the shortest length is 18 meters find there other two length of wire

Answer 1

Ratio between three different current wires =3:2:7

Shortest length =18 metres.

Let the common factor of the ratio be x.

Then length of the smallest wire =2x metre.

Given,the length of the smallest wire is 18 metres.

=>2x=18

therefore x=9 metres.

length of the first wire is 3×9=27 metres.

Length of the third wire is 7×9=63 metres.
