Question

The cost price of a dozen mangoes is equal to the selling price of 10 mangoes. The selling price of apples per piece is the cost of a mango (per piece). If the profit % made on selling an apple is half that of selling a mango, then what is the cost (in Rs.) of an apple if the selling price of one mango is Rs. X?

Answer 1

Answer:

(0.909090....) X

Step-by-step explanation:

Given

C P of one mango = X , Let the S P of Mango = Y

C P of 12 mangoes = S P of 10 mangoes

12 X = 10 Y

WKT

Profit % = ( S P - C P ) / C P * 100

             = ( Y/X - 1 ) * 100

             =  (12/10 - 1 ) * 100

             = 20 %

Now the Profit % of Apple is 20% / 2 = 10%

Let the S P of Apple be B and C P be A

Given

B = X

Now

B = 110% (A)

B = 1.1 A

A = B/1.1

A = (0.9090....) X
