Question

three numbers are in the ratio 3:4:5 if their product is 480 find the number

Answer 1

Hey there!

Let the no. be 3x,4x,5x respectively,
ATQ,
3x * 4x * 5x = 480
60x = 480
x  = 8

Now,
1st no = 3x = 3*8 = 24
2nd no = 4x = 4*8 = 32
3rd no = 5x = 5*8 = 40

Hope it helps!

Answer 2

let them be 3x. 4x. 5x
3x*4x*5x=480
shift them to the rhs
480/3*4*5=xxx
480/60
8=x^3
sol then
3x. 3*x
4x=4*x
5x=5*value of x
