A salesperson bought an item for Tk. X and marked it up 50%.
However, he could not sell the item during the first quarter and thus decided
to provide a discount of 20% on the marked price.
As the item remained unsold in the second quarters as well, he started
to charge 70% of the discount value.
What is the latest sales price of the item in terms of its buying price?
~~~~~~~~~~~~~~~
Let "p" be the bying price.
Then the marked price was 1.5p.
After 20% discount on the marked place the price was 0.8*1.5p = 1.2p.
When the salesperson started charging 70% of the discount value, the latest
sales price was 0.7*1.2p = 0.84p.
ANSWER. The latest sales price was 0.84p, in terms of buying price.
Solved.
