1. A calculator is sold for 345 at a profit of 15%. Find the cost price of the calculator. At what price must
it be sold to earn a profit of 25%?​

Answer 1

Step-by-step explanation:

+15% = 23/20. +25% = 25/20

23 = 345

1 = 15

25 = 375 answer

Answer 2

Answer:

CP = 300 , SP= 375

Step-by-step explanation:

CP = SP * 100/ 100 + profit%

CP = 345 * 100 /100+ 15

CP = 34500/ 115

CP = 300

300 = SP * 100 / 100+ 25

300 * 125/100 = SP

SP = 275
