Answer 1

Answer:

Then by the given question, x-(x/4+x/3+2x/5)=3

or, x-(15x+20x+24x)/60=3

or, x-59x/60=3

or, (60x-59x)/60=3

or, x/60=3

or, x=60×3

or, x=180

please mark as brainliest answer

Answer 2

Let the no. of guests be x.

1/4x + 2/5x + 1/3x + 3 = x

15x+24x+20x/60 + 3 = x

59x/60 + 3 = x

59x + 180/ 60 = x

59x + 180= 60x

180= 60x - 59x

180 =x

So the answer is option b.

Hope it helps...
