Final answer:
To find the discount amount, we need to first find the original price of the watch before the discount. From there, we can subtract the selling price to calculate the discount amount.
Step-by-step explanation:
To find the discount amount, we need to first find the original price of the watch before the discount. Let's call this price P. We are given that the watch was sold for Rs 1656 after a 10% discount on the MP (marked price). This means that the selling price (SP) is 90% of the MP, which can be written as:
P - 0.10P = 1656
Simplifying this equation gives:
0.90P = 1656
Dividing both sides by 0.90, we find:
P = 1656 / 0.90 = 1840
Therefore, the original price of the watch before the discount was Rs 1840. To find the discount amount, we subtract the selling price from the original price:
discount amount = P - SP = 1840 - 1656 = 184
