Question

a factory produces electric bulb if one out of 9 bulbs is defective and the factory produces 810 bulb per day find the ratio of the number of the defective bulb to the number of the non defected bulb produced in a day.​

Answer 1

Answer:

Step-by-step explanation:

№ of defective bulbs out of 9 bulbs = 1

The ratio of defective bulbs to the total № of bulbs = 1:9

Total № of bulbs produced = 810

Let the № of defective bulbs be x

Then the ratio is x:810

Now 1:10 = x:810

⇒10x =810

⇒ x = 810/10

∴ x = 81

∴The № of defective bulbs = 63
