1. Yes, the satin pyjama set gives you that luxurious feel and is amazingly soft and comfy. Besides, the fabric auto-regulates the temperature, meaning it can keep you warm when you’re cold and vice-versa

   please make me brainlylist

   Step-by-step explanation:

   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
