Question

A shopkeeper bought 300 apples at 80c each.30 apples got rotten and the remaining were sold at the market for 20c each.Find the buying price

Answer 1

cost: (40*40)+400 = 2000

after 10% profit : 2000* 110/100 =2200

40 apple= 10/3 dozen

now sell-able apple : 40dozen - 10/3 dozen = 110/3dozen

therefore, we need to sell 110/3 dozen at total rate of 2200 rupees.

that means  (2200) / (110/3)   = 60 Rupees
