Question

Chocolates are bought at 9 for a rupee and an equal number more at 11 for a rupee. if these are mixed and sold at 10 for a rupee, then the loss or gain percent is

Answer 1

Hey friend
here is your answer

let the no. of chocolates be "k".

so,
the total price of the chocolate at rs. 9 = 9 × k
similarly
the total price of the chocolate at rs. 11 = 11 × k

now if they are sold together then the average price of each chocolate
= rs. ( 11k + 9k )/2k
= rs. ( 20k )/2k
= rs. ( 10 )

so, cost of 1 chocolate = rs. 10

and if each chocolate is sold at rs. 10

then there is neither loss nor profit in the shipping of the chocolate.
