Question

A shopkeeper gives 10% discount on all items. If the discounted price of a shirt is Rs. 90, find the original price of the shirt.

Answer 1

Answer:

100.

Step-by-step explanation:

Discount given by shopkeeper = 10%

Discounted price = x - $\sf\dfrac{10x}{100}$

Discounted price = $\sf\dfrac{90x}{100}$

Now,

If the discounted price of shirt is Rs 90.

Then,

Marked Price = $\sf\dfrac{90x}{100}$ = 90

Marked Price , x = Rs 100.

Answer 2

Answer:

₹100

Step-by-step explanation:

Let the original price be x

Discount = 10%

So money needing to be paid = 90%

So,

90% of x = ₹90

=>90/100 • x = ₹90

=> x = ₹90 ÷ 9/10

=> x = ₹90 • 10/9

=> x = ₹900/9

=> x = ₹100

So the original price of the shirt is ₹100
