Question

A traders sales radio for rs 660 at a profit of 20% find out the purcheasing price of radio

Answer 1

Answer:

CP of the radio is rs.550.

Step-by-step explanation:

Given, SP = 660rs ; Profit % = 20%

CP = 100 / ( 100 + gain % ) × SP

after putting the values

CP = 100 / 120 × 660

CP = 100 × 55

CP = 550 ans.

on verifying

gain % = ( gain + 100 / CP )

( gain = 660 - 550 = 110 )

after putting the values

gain % = ( 110 × 100 / 550 )

gain % = 11000 / 550

gain % = 20%

hence verified

hope this answer helps you dear....take care!
