Problem : To find the cost price (CP) of the gold bracelet.

Solution:

Data Provided: Selling Price and Loss %

Find : CP ?

If loss is 20%, it means that if the cost price is ₹100, the loss incurred is ₹20.
If CP is ₹100, then SP is ₹80 , it means the selling price is 80% of the cost price.

When SP is ₹80, CP = ₹100
When SP is ₹14,500
CP = (100/80) × 14,500 = 18,125
CP = ₹18,125

Answer: The cost price of the chair is ₹18,125.

Another Method:

The selling price is calculated as 80% of the cost price (since 100% – 20% = 80%).

So, 0.8×18125=14,500.

Hence, the cost price of the gold bracelet is ₹18,125.
