A person wants to buy 10 chairs. The total cost of 10 chairs is ₹4,500. After bargaining, the shopkeeper agrees to decrease the cost of each chair by 20%. Then, the person purchased 10% more chairs. What will be the cost of the chairs that he purchased?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ₹3,960.
Given that, cost of 10 chairs = ₹4,500
⇒ Cost of 1 chair = ₹450
According to the given question,
New cost of each chair after bargaining = 80% of 450
⇒ = 360
The number of chairs the person bought after bargaining = 110% of 10
⇒ = 11
New total cost of 11 chairs = 11 × 360 = 3960
Hence the new cost of the chairs is ₹3,960.
