I decided to give novels as presents to my friends on Christmas. Since the prices of novels decreased by 25%. I can purchase 4 more novels for Rs. 600. What is the original and new price of the novel? Correct Answer Rs. 50/novel, Rs. 37.5/novel

Let X be the novels bought by me earlier.

Price per novel = 600/X

ATQ,

New price of the novel  = (600/X) – 25% of (600/X)

⇒ 450/X

Also New price per novel = 600/(X + 4)

∴ 450/X = 600/(X + 4)

⇒ X = 12

Old price = 600/12 ⇒ Rs. 50/novel

New price = 600/(12 + 4) ⇒ Rs. 37.5/novel

Statement: Hindustan Unilever and Nestlé plan to selectively increase prices of their products to take into account higher crude oil and petrol costs, the rupee’s depreciation against the dollar and more expensive commodities such as wheat. If crude remains where it is and if the rupee has depreciated, of course, there are headwinds as far as costs are concerned. I. Nestlé India’s logistics providers are looking to renegotiate rates after record-high petrol and diesel prices. Nestlé declined to comment on when and by how much prices would increase.  II. Nestlé commented that HUL had dropped prices in November after the Goods & Services Tax was introduced last year and an increase in prices now would likely not hurt consumers.  III. Petrol prices have crossed Rs 90 a litre in Mumbai on increasing global prices of crude oil, of which India is a net importer, further impacted by the falling rupee.
