Explanation:

- The shopkeeper sold two articles for Rs 9471 each, one with a 23% gain and the other with a 23% loss.

- To calculate the overall loss or gain, we need to consider the formula for such scenarios: Overall Loss or Gain % = [(Loss % × Gain %) / 100].

- Here, Loss % = Gain % = 23%. So, Overall Loss % = [(23 × 23) / 100] = 5.29%.

- Since the product of loss and gain percentages is positive, it results in an overall loss.

- Now, let's analyze the given options:

- Option 1: 5.29% gain (incorrect, as it's a loss, not a gain)

- Option 2: 5.29% loss (correct - overall loss)

- Option 3: 6.29% loss (incorrect, calculated loss is 5.29%)

- Option 4: 6.29% gain (incorrect, as it's a loss, not a gain)
