​

Answer 1

Steps:

Let the number of bulbs with damaged bulbs be x

x-10% of x = 3600

x- 1x = 3600

10

Common factor will be 10

10x-1x = 3600

10

9x = 3600

10

x = 3600×10

9

x = 4000

Let the number of total bulbs produced be y

y-20% of y= 4000

y- 1y = 4000

5

Common factor will be 5

5y - 1y = 4000

5

4y = 4000

00 5

y = 4000×5
