the other two be sold so as to gain
20% on the whole transaction ?​

Answer 1

Answer:

two fans are sold at 405 rupees

Answer 2

Step-by-step explanation:

C.P. of one item = Rs. 450, C.P. of three items = 3 x Rs. 450 = Rs.1350

Gain on the whole transaction = 20% 

∴ S.P. of the three items = 1350×120/100=Rs.1620

C.P. of 1 item = Rs. 450, Loss = 10% 

∴ S.P. of that item = 450×90/100=Rs.405

∴ S.P. of the remaining two items = Rs.1620-Rs.405=Rs.1215 

C.P. of these two remaining items =2×Rs.450=Rs.900

∴ Gain on these two items = Rs.315 

Gain % = 315/900×100=35%
