To find the weight used by the shopkeeper, we can set up the following equation:br /(X - W) / W = 6 + 18/47%br /First, let's convert the percentage into a decimal:br /6 + 18/47% = 6 + (18/47) * 0.01 = 6 + 0.0003829787 ≈ 6.0003829787br /Now, we can rewrite the equation:br /(X - W) / W = 6.0003829787br /Cross-multiply:br /X - W = 6.0003829787 * Wbr /Now, let's solve for X:br /X = W + 6.0003829787 * W X = 1 * W + 6.0003829787 * W X = 7.0003829787 * Wbr /br /We need to find the weight that is approximately 7 times the actual weight (W). The weight closest to 7 times W is 940 grams, which is option (A).br /So, the shopkeeper is using a weight of 940 grams.
