The inflation index of Country A in 1990 relative to 1995 was 5. Meaning that the ratio of dollars spent for goods during 1990 compared to the dollars spent for the same goods during the year 1995 is 1:5.
Similarly inflation index in country B for the year 1995 relative to 1990 was 9 and the inflation index in country C for the year 1995 relative to 1990 was 13. Price of a pair of shoes was $72 more in 1995 than in 1990 in all three countries. What was the ratio between the price of the
pair of shoes in Country A, Country B and Country C in 1995?

Answer 1

Answer:

The ratio between the price of the  pair of shoes in Country A, Country B and Country C in 1995 is 30:27:26

Step-by-step explanation:

Let the cost of the shoe be x , y , z in country A, B , C respectively in 1990.

In 1995, they became 5x, 9y, 13z due to inflation

(that's what the index meant).

Now,

The difference is 4x, 8y, 12z

which is all the same 72$ .

From this,

x=18 ;

y= 9 ;

z=6 ;

5x=90;

9y = 81;

13z= 78 ;

90:81:78 = 30:27:26

So, the ratio between the price of the  pair of shoes in Country A, Country B and Country C in 1995 is 30:27:26
