Answer 2

Step-by-step explanation:

case 1 :

cost price = 12000

By selling it gain% = 15%

formula

c.p×(100+gain%/100)

12000(100+15%/100)

12000(115/100)

12000×115/100

120×115(two zeros was cancelled)

13800 was paid by subash to sachin

case 2:

subhash purchased the tv for 13800,so

c.p = 13800

gain% = 10%

formula

cp×(100+gain%/100)

13800(100+10/100)

13800(110/100)

138×110(two zeros was cancelled)

15180 rupees was paid by aravind
