Question

an electrician uses tiny red and green bulbs in the ratio 3:5 to make a long chain of lights . if he used 1592 totally, how many red and green bulbs does he use ?

Answer 1

Step-by-step explanation:

Ratio of bulbs = 3:5

Total bulbs = 1592

Red bulb = 3:5+3 = 3:8 = (3/8)×1592 = 597

Blue bulb = 5:5+3 = 5/8 = (5/8)×1592 = 995

Hence number of red bulb is 597 and blue bulb is 995
