Question

25,35 and x are in a continued proportion. What is the value of x?

Answer 1

45 is the correct value

Answer 2

25 : 35 : x are in continued proportion.

Then,

a / b = b / c

==> b² = ac

==> 35² = 25 * x

==> 1225 = 25 x

==> x = 1225 / 25

==> x = 49

The value of x is 49

Hope it helps you
