Q:
# The prices of two radios are in the ratio x:yWhen the prices are both increased by £20, the ratio becomes 5:2When the prices are both reduced by £5, the ratio becomes 5:1Express the ratio x:y in it's lowest terms.

Accepted Solution

A:

When the prices of two radios are increased by 20 we got the equation as 2x-5y=60.
When the prices are reduced by 5 we got another equation as x-5y=60.
By equating these two we will get zero for x and -twelve for y. the lowest terms of ratio is 0:-12.
