Hi ,
This problem related to proportion:
Proportion:
_________
The equality of two ratios is called
Proportion.
In a proportion , the first and fourth
terms are known as Extremes , while
second and third terms are known as
Means.
If a : b = c : d , we write a : b : : c : d
and we say that a, b , c , d are in
proportion.
Then
a × d = b × c
According to the given problem:
18 : 30 : : 36 : x
a =18 ;
b = 30 ;
c = 36;
Let d = x ;
18 × x = 30 × 36
x = ( 30 × 36 )/ 18
x = 30 × 2
x = 60
Therefore required number = d = x = 60
I hope this will useful to u.

Answer: The answer is 66
Step-by-step explanation:
Let the first number be x
The second number is 2x-6
18*2-6 = 36-6= 30
Similarly, 36*2-6= 72-6=66
I hope this helps you.
