Answer

B

Explanation

Let marks price of item II= 100x
Let mark price of item III= 100y
`:. 100x+100y=6000`
`x+y=60 " "...(i)`
And `732x-84y=420`
`6x-7y=35" "...(ii)`
From (i) and (ii)
`y=25` brgt `x=35`
`:.` M.P of iem II= 3500
M.P. of item III = 2500
Required `%=(3500-2500)/(2500)xx100`
`=(1000)/(25)=40%`
