Question

A shopkeeper bought two items at ₹450 each. He sold one at the loss of 10%. At what price should he sell the other so as to gain 20% at the whole transaction

Answer 1

Answer: rs. 900

step-by-step explainaton :

c.p. of one item = rs 450

⇒ c.p. of three items = 3 × rs 450 = 1350

gain on the whole transaction = 20%

∴ s.p. of the three items =

1350

×

120

100

1350×120100 = 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
