Final answer:
To find the percentage saving for a customer who buys one of each product, calculate the amount saved on each item and then find the percentage of the combined savings compared to the original prices.
Step-by-step explanation:
To find the percentage saving for a customer who buys one of each product, we need to calculate the amount saved on each item and then find the percentage of the combined savings compared to the original prices.
First, let's calculate the savings on the first item. The price of the first item is Rs.100, and it is slashed by 15%. So the amount saved on the first item is Rs.100 x 0.15 = Rs.15.
Next, let's calculate the savings on the second item. The price of the second item is Rs.150, and it is slashed by 10%. So the amount saved on the second item is Rs.150 x 0.10 = Rs.15.
Now, let's find the combined savings. The total savings is Rs.15 + Rs.15 = Rs.30. To find the percentage saving, we divide the total savings by the sum of the original prices, which is Rs.100 + Rs.150 = Rs.250. The percentage saving is (Rs.30 / Rs.250) x 100 = 12%.
