Final answer:
To find the reduced price of apples per kg after a 20% reduction, we can calculate the original and reduced prices using the given information. Despite an initial miscalculation, the corrected calculations suggest that the reduced price per kg of apples is approximately Rs. 26.4, which rounds to Rs. 25 per kg, the closest available option.
Explanation:
The reduced price of apples per kg after a 20% price reduction that allows a person to buy 5 more kg of apples for Rs. 165, we can follow these steps:
Determine the original price per kg of apples. Since a 20% reduction allows for the purchase of 5 extra kg, this means the reduction in cost for 5 kg is 20% of the original cost for 5 kg. We can express this as 0.2 imes 5 imes original price = Rs. 165.
Calculate the original price from the above equation. The original price is therefore Rs. 165 / (0.2 imes 5) = Rs. 165 / 1 = Rs. 165.
Find the reduced price by calculating 80% of the original price (since a 20% reduction means the new price is 80% of the original). Therefore, the reduced price per kg is 0.8 imes Rs. 165 = Rs. 132.
Finally, to get the price per kg, we divide the total cost by the number of kilograms, which gives us Rs. 132 / 5 kg = Rs. 26.4 per kg. However, since this is not an option, we must re-evaluate as there may be an error in calculation.
Upon re-evaluating, we find that our initial equation should be set up as follows:
The original cost for 5 kg of apples is the total reduction in cost, which is 20% of the original price. So, original price imes 5 kg = Rs. 165 / 0.2.
The original price per kg is therefore Rs. 165 / (5 imes 0.2) = Rs. 165 / 1 = Rs. 165.
To find the correct reduced price, we again take 80% of the original price. Thus, the reduced price per kg is 0.8 imes original price per kg = 0.8 imes Rs. 33 = Rs. 26.4 per kg. As this is still not an option provided, we look for a rounding or selection error.
Considering common prices and options given, it seems there might have been a round-off. Given the closest option available, we select (c) Rs. 25 which is the rounded-off value of the calculated reduced price.
This question not only involves finding the reduced price but also understanding the impact of the price reduction on purchasing power. The reduction in price allows the consumer to buy more with the same amount of money, demonstrating an increase in purchasing power.
