Question

In Norway, when the price of eggs dropped by 20%, 20 more eggs could be obtained for 20 korner. what was the price of 1 egg earlier?

Answer 1

Answer:

1/4

Step-by-step explanation:

let the price/egg be 100x

reduced price =80x

20/80x-20/100x = 20

solve the equation you will get x=1/400

so 100×1/400 =1/4

Answer 2

Concept

Percentage in mathematics is the number that is expressed as a fraction of 100. For calculating percentage of a number we divide the number by the whole and then multiply it with 100. Parts per hundred is also called as Percentage.

Given

When Price dropped by 20%, 20 more eggs could be obtained for 20 korner

Find

Price of 1 egg earlier

Solution

Let the price of egg be 100x

Price was reduce by 20% = 100x - 20x

=80x

Number of eggs that he can bought = 20/80x

ATQ

20/80x - 20/100x = 20

1/80x - 1/100x = 1

5-4/400x = 1

1/400x = 1

x = 1/400

We took the price of egg to be 100x

= 100 * 1/400

= 1/4

The price of 1 egg earlier was 0.25 or 1/4.
