Question

Correct option is B 35% 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 = 100 1350×120 ​ =
Rs.1620 C.P. of 1 item = Rs. 450,
Loss = 10% ∴ S.P. of that item = 100 450×90 ​ =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 % = 900 315 ​ ×100=35%​

Answer 1

Answer:

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 =

100

1350×120

=Rs.1620

C.P. of 1 item = Rs. 450, Loss = 10%

∴ S.P. of that item =

100

450×90

=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 % =

900

315

×100=35%
