Question

three numbers are in ratio of 2:3:5. if sum of their cubes is 34560 find the number

Answer 1

Step-by-step explanation:

let the no be x

so (2x)³+(3x)³+(5x)³ = 34560

8x³+27x³+125x³= 34560

160x³= 34560

x³= 34560/160

x³= 216

x = ³√216

x= 6

so numbers are 2×6 , 3×6 and 5×6

= 12,18,30
