Ramees claims to sell goods at cost price but uses 900 grams instead of a kilogram. What is his percentage profit?
Show answer Hide answer
Answer: C. 11 1/9%
Explanation
Selling nine hundred grams while claiming it is a full kilogram creates a false weight discrepancy. The merchant makes a profit of one hundred grams for every nine hundred grams actually dispensed. Dividing one hundred by nine hundred and converting to a percentage yields eleven and one ninth percent. Dishonest trade practices involving faulty weights alter the effective profit margin calculations. Percentage profit in weight fraud is calculated as the error amount divided by the false weight sold. Fractions like one ninth convert into recurring mixed percentage numbers in commercial mathematics.
Weights and measures inspectorates regulate commercial scales to prevent fraudulent short weighing practices. Historical trade regulations heavily penalized merchants using inaccurate measurement standards in markets. Consumer protection laws require transparent labeling and accurate quantities in all retail transactions. Option A rounds the recurring decimal percentage incorrectly ignoring the exact fraction. Option B miscalculates the fractional denominator by using the true kilogram instead of the false weight. Option D underestimates the percentage profit derived from the short weight measurement error.
