Question

In a factory the ratio of number of defective bolts produced to the number of good bulbs is 1: 10. In one hour the factory produced 330 bolts. find the number of defective bulbs produced by the factory in an hour.​

Answer 1

Answer:

according to the equation the ratio is 1:10......therefore on according to the question.....

let the no. of defective bulbs be x..

x/330=1/10

x=33

Answer 2

The number of defective bulbs produced by the factory in an hour is 30.

Step-by-step explanation:

Let x be the number of defective bolts produced and

10 x be the number of good bulbs produced.

In one hour,

The factory produced = 330 bolts

To find, the number of defective bulbs produced by the factory in an hour = ?

According to question,

x + 10x = 330

⇒ 11x = 330

⇒ x = $\dfrac{330}{11}$

⇒ x = 30

The number of defective bulbs produced by the factory in an hour = 30

Thus, the number of defective bulbs produced by the factory in an hour is 30.
