Let the number of articles be = x units Then the cost of each article = Rs (2x+3) Total cost = Rs 90 x(2x+3)=90 x(2x+15)-6(2x+15)=0 (x-6)(2x+15)=0 x=6 or x = -15/2 since x is number of articles it cannot be negative or a fraction Hence x = 6 The number of articles produced = 6 The cost...

Let the number of articles be = x units

Then the cost of each article = Rs (2x+3)

Total cost = Rs 90

x(2x+3)=90

x(2x+15)-6(2x+15)=0

(x-6)(2x+15)=0

x=6 or  x = -15/2

since x is number of articles it cannot be negative or a fraction

Hence x = 6

The number of articles produced = 6

The cost of each article =2*6+3 = Rs 15
