Question

Some marbles are purchased at the rate of 11 for 10 and the same number at the rate of 9 for
10. If the whole lot is sold at one rupee per marble, find the loss or profit percentage on the
whole transaction.
them at a gain equal to the selling price​

Answer 1

Answer:

profit / loss percentage = 0%

Step-by-step explanation:

first lot, 10 marble cost = 11

second lot, 10 marble cost = 9

Total cost = 11 + 9 = 20

Total marbles = 10 + 10 = 20

one marble cost = 20/20 = 1

Total sales amount @1 = 20× 1 = 20

profit/ loss = 20 - 20 = 0
