Hi,
___________________________
If a : b = c : d , we write a : b : : c : d
and we we say that a, b , c , d are
in proportion.
We have ,
Product of Extrems = product of Means
ad = bc
_______________________________
According to the problem given,
15 : 66 : : 185 : x
Therefore ,
15 × x = 66 × 185
x = ( 66 × 185 ) / 15
After cancellation, we get
x = 814
Option ( 4 ) is correct.
I hope this helps you.
:)
