What is the discount that Rohan should offer on the remaining ₹8,000 of a laptop priced at ₹48,000, given that, he has already given a 12% discount on the first ₹28,000 and 8% discount on the next ₹12,000 to match the discount amount of 9.5% given on the total price?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. ₹240.
Let's calculate the total discount Rohan needs to give to achieve a 9.5% discount on the total price of the laptop.
Total discount = 9.5% of 48000 = 0.095 × 48000 = 4560 rupees.
Now, let's calculate the discount Rohan has already given:
Discount on the first 28000 = 12% of 28000 = 0.12 × 28000 = 3360 rupees.
Discount on the next 12000 = 8% of 12000 = 0.08 × 12000 = 960 rupees.
Total discount given so far = 3360 + 960 = 4320 rupees.
Therefore, the remaining discount Rohan needs to give on the last 8000 rupees is:
4560 - 4320 = 240 rupees.
