Answer 2

Answer:

5000 bulbs

Step-by-step explanation:

Let the total number of bulbs produced be 100.

Then 20 bulbs are detective.

So 80 bulbs remaining.

10% of the 80 bulbs got damaged.

So no. of bulbs damaged is 10/100×80=8.

So no. of bulbs packed is 80-8=72.

If 72 bulbs were packed then total no. of bulbs produced is 100.

If 1 bulb is packed then total no. of bulbs produced is 100/72.

If 3600 bulbs are packed then total no. of bulbs produced is 100/72×3600=5000.

So, 5000 bulbs were produced by the factory.

Hope it helps you.
