Question

A furniture seller sold two dressing tables @rs 7200 out of them 20% profit obtained on 1 table and 20% loss on another how much profit or gain %is obtained in whole transactio

Answer 1

The loss on entire transaction is 4%.

Sp of 1st table = SP of 2nd table = Rs.7200  (GIven)

Profit on first table = 20%

Therefore,  

CP = SP ( 1 + gain/100)

= 7200 ( 1 + 20/100)

= 6000

Loss on second table = 20%

Therefore,  

CP = SP ( 1 - loss/100)

= 7200 ( 1 - 20/100)

= 9000

Total C.P = 6000+9000 = 15000

Total S.P = 7200+7200 = 14400

Loss = CP - SP

= 15000 - 14400

= 600.

Loss% = Loss × 100/cp

= 600 × 100/15000

=  4

Thus, the loss on entire transaction is 4%.
