Question

Three numbers are in the ratio 2:3:5. If the sum of their cubes is 1280.Find the three numbers.

Answer 1

Answer:256,384,640

Explanation:

Take the ration sum 2x+3x+5x=1280

When we add we get 10x=1280

Then find x by. x=1280/10=128

Then substitute this x value to the ratios 2x=2*128 =256

3x=3*128=384

5x=5*128=640
