Question

the total cost is C= 200 + 20 x and revenue is R= 800 + 5x find the point of no profit no loss​

Answer 1

when there is no prOfit no loss then

C = R

200+ 20X = 800+5 X

20X- 5X = 800-200

15X = 600

X = 40

At the point X= 40 C will be equal to R

Hence there is no profit no loss

Answer 2

Given,

cost price : C= 200 + 20 x

Revenue that is selling price : R= 800 + 5x

No profit or no loss occurs if and only if :

                                     C = R

           ⇒          200 + 20 x = 800 + 5x

           ⇒                     15x = 600

             Therefore , x =40

At a point where x = 40, no profit or loss occurs.
