Question

Four sizes of scaled text are shown. What is the unknown scale size?

Answer 1

The answer is 1.067. Hope it's not too late.

Answer 2

font size of top line will be 1.067

Explanation:

Scale factor between 4th line text size to the 3rd line text will be

=
`(0.937)/(0.878)=1.067`

Scale factor between 3rd line and second line will be =
`(1)/(0.937)=1.067`

Therefore, scale factor between 2nd and 1st text size will be =
`(x)/(1)=1.067`

x = 1.067

It reveals that the font size of top line will be 1.067
