Question

The price of a sweater is increased by 8% .If its increased price is ₹ 1566, find the original price.

Answer 1

solution:-

(1566×100)/108

= 156600/108

= 1450
thats simply

the original price is 1450rs

Answer 2

Let Original price= x
New price= 1566₹
% change= 8%
% change sign= +ve(As price is Increased)

x + 8% of x = 1566₹
=> x + (8/100)× x = 1566₹
=> x + (2x/25)= 1566₹
=> 27 x= 1566 × 25
=> x= (1566×25)/27
=> x= ₹1450.

•°• Original price= ₹1450

Points to remember:

•New price = Original price+(Original price × %change)
{Replace '+' with '-' when %change sign is '-ve}

•% change= x%= (x/100)

•x% of y= (x×y)/100= xy/100
