Suhana sells a sofa set for ₹9600 making a profit of 20%. What is the C.P. of the sofa set?

Solution:

Given, Suhana sells a sofa set for ₹9600

She makes a profit of 20%

We have to find the C.P. of the sofa set.

Let the cost price be ₹100

Profit = 20% of cost price

= (20/100) × 100

Profit = ₹20

Profit = selling price - cost price

20 = selling price - 100

Selling price = 20 + 100

Selling price = ₹120

When CP = ₹100; SP = ₹120

If SP = ₹9600, CP = ?

CP = (100/120) × 9600

= (5/6) × 9600

= 5 × 1600

= ₹8000

Therefore, CP = ₹8000
