b) Original price - 5 Rs. Per kg
c) current consumption – 50 kg
d) Current price - 4 Rs. Per kg.​

Answer 1

Answer:

Original price-5 Rs. Per kg

Step-by-step explanation:

Let original price per kg =x

then price occured after reduction = x-20x/100

= 80x/100 =4x/5

Quantity of sugar if he sold it at original price = 200/x

Quantity of sugar when he sold at reducted price = 200/4x/5 = 200×5/4x = 250/x

so, from the data

250/x =200/x+10 (we wrote 10 here because he told that he enbles to buy 10kg more sugar for Rs200)

250/x - 200/x = 10

250-200/x = 10

50/x = 10

x = 50/10

x =5 Rs

Original price = 5 Rs per kg
