1. Answer:

   i use 8xwater than salt in dough

   if i use 100gm salt in dough for 30 person

   total mixture is of 9ml

   find

   how much i need water??

   let’s assume salt as (x)

   water as 8x

   100 gm = 100ml water

   eq. x + 8x = 900ml

   9x = 900ml

   x = 900/9

   x= 100

   salt = x = 100ml

   water = 8x = 100×8

   = 800ml

   to make dough i need 800ml water
