a.4096
b.5832
c.4923
d.4913​

Answer 1

Step-by-step explanation:

Given  

624:1728::386:?

We know that from the given ratio product of means = product of extremes.

We need to find the unknown number in the given sequence.

             So 624 x x = 1728 x 386

       So 624 x = 667008

Now x = 667008 / 624

So x = 1068.92

So the missing number will be 1068.92
