If the revenue from pen sales is 500, then the revenue from pencil sales would be 200, making the combined rate 700. The revenue from pen sales went up 5%, so it is now 525. And the revenue of pencil sales went down 13%, so it is now 174. Your combined revenue would be 699, which is not 1% lower than 700. You needed to find a 693 in this calculation in order to confirm your answer.

If you try the ratio 2:1, you will see that if the revenue from pen sales is 200 and the revenue from pencil sales is 100, your combined revenue would be 300. Adding 5% to pen revenues and reducing 13% to pencil revenues would yield 210 and 87 respectively. If you sum both, you get a total revenue of 297, which is 1% lower than 300.

I don't know any easier way to solve this problem. The best way is always to attribute a quantity for one of the variables do the equation shown in that example.

Hope this helps!

Cheers.

The revenue from pen sales was up 5%, but the revenue from pencil sales declined 13%. If the overall revenue was down 1%, what was the ratio of pen and pencil revenues?
105 + 0.87x = 0.99(100 + x)  6 = 0.12x  x = 50
So, the ratio is 2:1

Are there any other ways to solve this?

I get 5:2
