Question

Various precious stones were used for the interiors .The
ratio of corals : turquoise : jade was 3:4:5.If the total
weight of the stones were 240kg ,Find the weight of
each stone.

Answer 1

Step-by-step explanation:

let weights of stones be 3x , 4x and 5x

So 3x+4x+5x = 240

12x = 240

x = 240/12 20

So corals weight is 3x = 3X20 = 60

turquoise weight is 4x = 4X20 = 80

jade weight is 5x = 5X20 = 100
