Answer 2

Answer:

He purchase the tv set for Rs. 5400

Step-by-step explanation:

Let the cost price be x

Discount% = 25%

So, Discount = $25\% x = \frac{25}{100}x=\frac{1}{4}x$

We are given that If he gets a discount of 25%, he saves Rs1800.

So, $\frac{1}{4}x = 1800$

$x = 1800 \times 4$

$x = 7200$

Now we are supposed to find the price at 20% discount

CP = 7200

Discount % = 25%

So, Price After discount = $7200-25\% \times 7200 = 7200-\frac{25}{100} \times 7200=5400$

Hence he purchase the tv set for Rs. 5400
