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

The concept of linear equation and ratios is used to solve for the price of radios. The price of two radios are and .

Given information:

The ratio of prices of two radios is .

If the price of both the radios is increased by , the ratio of price would become 5:2.

The above condition can be written mathematically as,

If the prices are both reduced by , the ratio will become 5:1.

The above condition can be written mathematically as,

Add equation (1) and (2), to get the value of and as,

Solve for as,

Therefore, the price of two radios is and .
