A shopkeeper buys three products a, b, c and sells them at 20%, 30%, 40% profit, respectively. What is ratio of the selling price of these products, if the ratio of their cost prices is 4 : 3 : 2 ?

48 : 39 : 28

The ratio of their cost prices is = 4 : 3 : 2

After selling them at 20%, 30%, 40% profit, the selling price will be =

 \(\frac{4 × 120}{100}\)  :  \(\frac{3 × 130}{100}\)  :  \(\frac{2 × 140}{100}\)

A : B : C = 48 : 39 : 28
