Question

A shopkeeper decreases
the selling price of a ceiling
fan by 10% at the start of
winter. When winter is over, he
decides to raise the price back
to the original selling price. By
what percent would he need
to increase the lowered price
in order to do this?​

Answer 1

Answer:

0.1%

Step-by-step explanation:

let the S.P =x

x-10x/100=90x/100=9x/10

9x/10+p% =x

p%=x-9x/10

p/100=x/10

p=10x =0.1%
