Question

At 20% profit an object is sold at 330. Find it's cost price
​

Answer 1

Answer:

cp = 275

Step-by-step explanation:

let the cp be x

profit = 20% = 20/100× x

sp = 330

a/q

x + 20/100 × x = 330

100 x + 20 × / 100 = 330

120 x / 100 = 330

120 x = 330 ×100

120 x = 33000

x = 33000/120

x = 275

cp = 275
