Answer 1

Answer:

Step-by-step explanation:

There are two cottage industries A and B having the same number of

employees.

In A = 4+2x

If the total cost of production on that day was  390.

390 = x(2x + 4)

390 = 2x² + 4x

2x² + 4x - 390 = 0

2x² + 30x- 26x - 390 = 0

2x ( x + 15) - 26( x+ 15) = 0

(2x -26) (x+15)

x = 13,  x = -15

Production is cant be in "-" ve so the x = 13

287 /2 =x
