Question

47. Find the change in the percentage profit for a fruit vendor who, after finding 20% of the fruits
rotten, increased his selling price by 10% over and above 15% that he was already charging?
(a) – 15 (b) + 11.5 (c) – 13.8 (d) + 13.8 (e) Cannot be determined​

Answer 1

Answer:

c

suppose rate 10 per kg and total kg = 10

earlier selling 10 x 10 = 100 + 15% = 11.5 per kg, profit = 115

now remaining fruits r 8 kg

increased rate 10%

11.5+11.5x10/100=12.65

12.65 * 8 kg = 101.2

loss = 115-101.2= 13.8
