The grocer bought 24 kg of coffee beans at X and sold 16 kg(as one-third of stock
got spoiled) of the stock for 200$ per kilo. The total profit made is twice the cost.

Profit = Selling Price - Cost Price So, \(16*200 - 24*x = 2*24x\)

This can be further simplified as \(72x = 16*200\) -> \(x = \frac{16*200}{72} = \frac{400}{9}\)

Therefore, the price at which the grocer bought the coffee beans is $\(44\frac{4}{9}\) (Option C)

There is a small calculation mistake in the end.

16 * 200/72 = 400/9

Solution


Given:
    • Cost price of 24kg of coffee beans = 24 * X
    • Sold the rest \((\frac{2}{3}) * 24kg\) at a selling price of $200 per kg
    • Profit = 2 * cost price

To find:
    • The value of X

Approach and Working:
    • Total CP = 24X
    • Total SP = \($200 * 24 * \frac{2}{3}= $3200\)
    • Profit = $3200 – 24X = 2 * 24X
      o Implies, \(X = \frac{$3200}{72} = \frac{$400}{9} = $44\frac{4}{9}\)

Hence, the correct answer is Option C

Answer: C
