Question

If 36, 54, x are in continued proportion. Find the value of x.

Answer 1

Answer:

36 : 54 = 54 : x

36/54 = 54/x

2/3 = 54/x

x = (54 × 3)/2 = 27 × 3 = 81

Answer 2

Answer:

Given,

a = 36 ; b = 54 & c = x

we know,

continued proportion = a:b::b:c

=> 36:54::54:x

=> 36/54 = 54/x

=> 36×x = 54×54

=> x = (54×54) / 36

=> x = 2916/36

=> x = 81

Answer :- The value of x is 81.
