Khushi went to purchase a mixer. The marked price of the mixer was ₹6,000 and 20% flat discount was offered on it by the shopkeeper. How much does Khushi have to pay for the mixer?

₹4,800

MP = Rs. 6000

Discount = 20%

SP = 6000 x \(\frac{100 - 20}{100}\) = 6000 x \(\frac{80}{100}\) = Rs. 4800.

Hence, She Paid Rs. 4800 for the mixer.
