Question

A fabric cotton and synthetic fibres are in the ratio 2 :3 by weight. If the weight of the cotton fibres is 30 grams. Express this statement as a linear equation in two variables
a. 3x-2y =0 b. 3x+2y =0 c. 2x-3y = 0 d. 3x-2y = 30

Answer 1

we have given data as

fabric cotton =fc

synthetic fiber=sf

weight of cotton fiber= 30 gram

ratio is given as 2:3

hence fc=2y

          sf=3x

now equation is

3x -2y=30

hence option (d) is correct
