Answer 1

Answer:

Original price = 13.33 Rs

Reduced price = 12 Rs

Step-by-step explanation:

Let x be Original price of potatoes and Y be original amount of potatoes

Initially,

Finally =

9x/10 * (y+2) =240

x * (y+2) = 240*10/9

xy + 2x = 800/3

240+2x = 800/3

2x = 800/3 - 240

2x = 80/3

x = 40/3

x = 13.33

solve for y

13.33 * y = 240

Y = 240/13.33

Y = 18Kg

Reduced prices

x = x*9/10

x = 13.33*9/10

x = 12 Rs
