A merchant had Rs 78,592 with her. She placed an order for purchasing 40 radio sets at Rs 1,200 each. How much money will remain with her after the purchase?

The total cost of 40 radio sets can be calculated by multiplying Rs 1,200 and 40.

Answer: The merchant after placing an order of purchasing 40 radio sets at Rs 1200 each will remain with Rs 30,592 after her purchase.

Let's find how much money will remain with her after the purchase.

Explanation:

Cost of one radio set = Rs. 1200
Therefore, cost of 40 radio sets = Rs. 1200 × 40 = Rs. 48,000
Total amount with the merchant = Rs. 78,592
Amount spent to purchase 40 radios = Rs. 48,000
Remaining amount after purchase = Total amount - Amount spent

= Rs. (78,592 – 48,000)

= Rs. 30,592

Thus, the merchant after placing an order of purchasing 40 radio sets at Rs 1200 each will remain with Rs 30,592 after her purchase.
