please any one answer this...​

Answer 1

Answer:

ans D

Step-by-step explanation:

4 x 8 x 16 = 512 and their ratio is

1:2:4

Answer 2

Answer:

It is said that three nos. are in ratio. And their product is 512.

Then,

Let 1x, 2xand 4x are the nos. in ratio.

1x*2x*4x=512

8x³=512

x³=512/8

x³=64

$x = \sqrt[3]{64} \\ x = 4$

Then,

1x=1*4=4

2x=2*4=8

4x=4*4=16

The nos. are 4,8and 16

So it should be D.

Hope this may helpful my friend.
