Question

by selling a dozen night suits for ₹4920, Ruby loses 18%. for what amount she sell each piece to gain 15% profit ?

Answer 1

If Ruby loses 18% by selling a dozen night suits for Rs.4920, she is selling it with the price of 82%(100%-18%)of real cost.
Let real cost of a dozen night suits be x
$\frac{82x}{100} = 4920$
x=4920*100/82
x=6000

Let y be real price of one night suit
y=x/12
y=6000/12=500

Let z be the price of one night suit with 15%profit

z=(115/100)y
z=500+115/100
z=575
Thus , she will get 15%profit when she sells each night suit for Rs.575
