What was the original frequency of a guitar string when given the frequency of a violin?

A violin string tuned to 485.0 Hz is found to exhibit 2.0 beats per second with a guitar string. The guitar string is then tightened, and the beat frequency is found to increase. What was the original frequency of the guitar string?

Chosen Answer:

487Hz

2 beats per second means that it’s a 2Hz different. Since the frequency of the beats INcreases when the string is tightened, that means that the string is already vibrating faster than the violin string.

    beat frequ=Fb=IFg-FvI=2hz..truble is u dunno which is higher Fg/Fv
    but if Fb incs when g-strng is titend..it means that Fg is increasing away from Fv
    So Fg=487Hz orig
