Question

Three numbers are in ratio 3:4:5. If their product is 480, Find the numbers.

Answer 1

Let the numbers be 3x , 4x and 5x
Product of numbers=480

3x×4x×5x=480

60x³=480

x³=480/60

x³=8

x=2

3x=3×2=6
4x=4×2=8
5x=5×2=10

Hence numbers are 6 , 8 and 10

Answer 2

Hi there!
Let the numbers be in terms of x.

Now we have 3x 4x and 5x

Acc. to the question:

3x X 4x X 5x = 480

》 60x = 480

》 x = 480 ÷ 60

》 x^3 = 8

》 x = 2 ( cube root of 8 is 2)

Now. 3x will be 3 times 2 》 3 x 2 = 6

Similarly, 4x = 4 x 2 = 8
and 5x = 5 x 2 = 10

Hence, the numbers are 6, 8 and 10.

I hope this helps. :)
