Correct Answer - Option 2 : 3500
Given:
A book B is bought for Rs. 500 more than book A, which was bought for 1500 less than C.
The ratio of price of B: C is 7: 9.
Book A is sold at a price C was bought for and B is sold for 3000.
Formula used:
Profit or Gain = Selling price – Cost Price
Loss = Cost Price – Selling Price
Profit percentage = (Profit/Cost Price) x 100
Loss percentage = (Loss/Cost price) x 100
Calculation:
Cost price of A, B, C
A = x,
B = x + 500,
C = x + 1500
Now selling price of A, B and C
A = x + 1500,
B = 3000,
C = y
ATQ,
(X + 500)/(x + 1500) = 7/9
⇒ X = 3000
As per question
3000 + 3500 + 4500 = 4500 + 3000 + y
⇒ Y = 3500
∴ selling price of C is Rs. 3500
