Let’s say the marked selling price was P.
After successive discounts of 30% and 20%, the actual selling price was 0.7*0.8*P = 0.56*P
This was 40% over the cost C, of the Minaudière.
So, C = (0.56*P)/1.4 = 0.4*P
That means, C:P = 2:5
The only option choices that show a 2:5 ratio are $80 and $200. So, C = $80 and P = $200.
How do you infer the ratio from P and C result then? By estimating or calculating that the ratio between 0,4 and 1,4 is equivalent to 2:5?

I'd say that if 80 was the smaller number in the ratio, then the larger number must be more than 2 (exactly 5/2) times larger - at least 160. So, the larger number in the ratio is 200 or 300. To find the smaller number in the ratio we just have to multiply the larger number by 2/5. We get 80 and 120, respectively. Only 80 is also on the answer sheet.

I hope this helped you!
