Question

An item was sold for Rs 3600 at 25% discount. Its marked price was?
1)4500
2)4800
3)2700
4)2880

Answer 1

let marked price be x
now,
25% of x = 3600
25/100x = 3600
x = 3600*100/25
x. =14400

Answer 2

Given the discount: 25%

Selling Price: Rs 3600

Marked price is the price of the item without discount.

Hence discount has to be applied on market price  

Let marked price be x

Step 1: Find discount in Rupees

Discount = $\frac{25}{100}*x=\frac x 4Rs$

Step 2: The formula for selling price is

Selling price = Marked Price - Discount  

3600=$x-\frac x 4=\frac{3x}4$  

x=$\frac{3600*4}3=4800$  

Hence Marked price of the item is Rs 4800 which is option (2)
