B Correct answer
Explanation

Gain = (True weight - False weight) / False weight * 100. Gain = (1000 - 940) / 940 * 100 = 60 / 940 * 100 = 600 / 94 = 300 / 47 = 6 18/47 percent.

AI explanation

Using the faulty weight profit formula, profit percentage is ((true weight minus false weight) divided by false weight) multiplied by 100. Substituting the given values, the calculation is ((1000 minus 940) divided by 940) multiplied by 100. This simplifies to (60 divided by 940) multiplied by 100, which equals (3 divided by 47) multiplied by 100. The result is $\displaystyle6\frac{18}{47}$ percent.
