total fluid needed in 24 hours = 4*80*50=16000 units
fluid for first 8 hours = half = 8000 units
rate=8000/8=1000
so it should be 3.

on 1st day burn kg.BW* % of burn * 4cc RL + 2000 cc D5W
infuse 1/2 first 8 hours, infuse 1/2 next 16 hours
surgery kaplan pg.10
so in this pt we have to add 2000 cc D5W, with this calculation we have to give 9000 in first 8 hours.

I think, In this question asked about rate of given solution....not the amount of solution to be given !
