Question

Three numbers are in the ratio 3:4:5 if the sum of their cubes is 46656 find the number

Answer 1

Let the three numbers be 3x, 4x, 5x

ATP

3x+4x+5x = 46656

= 12x = 46656

= x = 46656/12

= x = 3888

First number = (3×3888) = 11,664

Second number = (4×3888) = 15,552

Third number = (5×3888) = 174,960

Answer 2

Step-by-step explanation:

let 3:4:5 be x then, 3x,4x,5x

we know that,

3x+4x+5x=46656 (given)

12x=46656

23,328

now,x=23,328

3x=23,328*3=69,714

4x=23,328*4=92,952

5x=23,328*5=116,190
