Final answer:
Rashmi would prefer to purchase the Vidyut AC model, as its price after a 5% discount comes to Rs 23203.75, which is within her budget of Rs 24000 and is lower than the cost of the Zenith model after its discount.
Step-by-step explanation:
Rashmi is looking to purchase an air conditioner (AC) with good service, cost-effectiveness, and a spending limit of Rs 24,000. After considering the provided cost and special offers of the different AC models, the cost needs to be calculated for each option after applying discounts or adding additional charges.
- Alpha: Rs 22785 (cost) + Rs 3500 (annual maintenance) = Rs 26285
- Vidyut: Rs 24425 - 5% of Rs 24425 (discount) = Rs 23203.75
- Samurai: Rs. 23590 + Rs 500 (installation) = Rs 24090
- Zenith: Rs.24725 - 5% of Rs 24725 (discount) = Rs 23488.75
- Versa: Rs. 29900 (no additional costs but exceeds budget)
Considering Rashmi's budget of Rs 24000, the only models that do not exceed this price after including their respective additional costs or discounts are AC models Vidyut and Zenith.
Among these, Vidyut costs Rs 23203.75 which is less than Zenith's Rs 23488.75, making Vidyut the preferred choice for Rashmi as it fits her budget and likely meets her expectations for cost and good service.
