Since CP < SP

∴ Profit =1000−985=15

⇒ %P ≅985

15×100≅1.5

Answer 2

Answer:

Gain %age = 4%

Step-by-step explanation:

Cost of 1st chair after profit of 20% = 500 + 20/100 x 500

                                                             = 500 + 100

                                                             = 600 Rs.

Cost of 2nd chair after loss of 12% = 500 - 12/100 x 500

                                                            = 500 - 60

                                                            = 440 Rs.

Total gain/loss = Total C.P of both the chairs - (S.P of 1st chair + S.P of 2nd chair)

                 = (500 x 2) - (600 + 440)

                 = 1000 - 1040

                 = 40 Rs.

Gain %age = (Gain x 100)/C.P

                   = (40 x 100)/1000

                   = 4 %
