Answer 1

Answer:

Rs 140

Step-by-step explanation:

Define x:

Let the cost price be x

Find the selling price in term of x:

Profit = 1/2 of x = 1/2 x

Selling Price = Cost Price + Profit

Selling Price = x + 1/2 x = 3/2 x

Solve x:

Selling Price is Rs 210

3/2 x = 210

x = 210 ÷ 3/2 = Rs 140

Answer: The cost price is Rs 140
