Question

Three numbers are in the ratio 1:3:4 and the sum of their cubes is 11500.Find the numbers

Answer 1

Step-by-step explanation:

Let the 1x,2x&3x are the 3 numbers 

∴ sum of their cubes =x3+(2x)3+(3x)3

                                    =98+84

                                    =(36x)3

x3=3698784=2274

x=2744=14

∴3 numbers are 14,28,42
