Question

seeta sells dining set to Anita for 6000 and gains 20% for .how much should see sell it to increase their profit by another 5%

Answer 1

SP = Rs. 6000
Let CP be x 

So, we have x + x*20/100 = 6000
                     x+x/5 = 6000 
                     6x = 6000*5
                       x = Rs. 5000

So, CP = Rs. 5000
 So, to gain 25%

SP = 5000 + 5000*25/100
      = 5000 + 5000/4
      = 5000 + 1250
       = Rs. 6250

So, She should sell it for Rs. 6250 

Answer 2

CP=100/100+20*6000=5000

SP to gain 25%=100+25%/100*5000=6250rupees
