Answer 1

Answer:

here your answer.........

Step-by-step explanation:

let original price of sugar be (a)per kg

After reduction the price of sugar is

a-(a×20/100)

a-20a/100

100a-20a/100

80a/100=0.8a

According to question

80/0.8a=(80/a)+4

800/8a=(80/a)+4

100/a=(80/a)+4

(100/a)-(80/a)=4

20/a=4

4a=20

a=20/4=5

therefore the original price of sugar

is 5 per kg.
