Answer 1

Heya!

Here's Your Answer

Let The Number of Bulbs Be
12x
11x
10x

Then,

12x+11x+10x=4752
12x+21x=4752
33x=4752 Bulbs

X=4752/33
Therefore, X = 144

Hence,
Red bulb =12x=12*144=1728 Red Bulbs
Blue bulb=11x=11*144=1584 Blue Bulbs
Yellow Bulb=10x=10*144=1440 Blue Bulbs

Hope This Helps.......!!!! :-)
