A retailer sold a vacuum cleaner for 40% below its marked price. The sale price was 50% above the cost to the retailer. What is the ration of marked price to cost?

10 : 9

Step-by-step explanation:

Given that a retailer sold a vacuum cleaner for 40% below its marked price.

Let the marked price = P

40% below = (100 - 40)P/100

Sale price = 60P/100

Sale price = 0.6P

The sale price was 50% above the cost to the retailer.

That is, cost price = (100 + 50)0.6P/100

Cost price = (150)0.6P/100

Cost price = 1.5 × 0.6P

Cost price = 0.9P

What is the ratio of marked price to cost?

The ratio will be = P/0.9P

Multiply both the numerator and denominator by 10

Ratio = 10 : 9
