During a sale, a shopkeeper reduced the prices of all his goods by 25%. Calculate the normal selling price of a pair of shoes which was sold for Rs 1350 in the sale.

₹1,102.5

Step-by-step explanation:

Price of the shoe before the 25% off sale = ₹1350

Price of the shoes after 25% off sale = ₹1350- 25%

= ₹1,012.5

let be the real price x :

x - x × ( 25/100 ) = 1350

x - x × ( 1/4 ) = 1350

x - x/4 = 1350

4x - x / 4 = 1350

3x / 4 = 1350

3x = 1350 × 4

3x = 5400

x = 5400 ÷ 3

x = Rs 1800

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
