My take is 12.5%.
CP (14) = SP (10).
The discount offered on 70 apples = 420.
=> Disc on 10 apples = 60.
100 (CP) = 140 (SP) = 200 (MP).
=> 30% Disc and 100% Markup.
Now we have to half the markup and decrease the disc% by 5 points.
So, Disc = 25% and Markup = 50%.
=> CP = 100.
SP = 150.
MP = 112.5
=> P% = 12.5

@hemant_malhotra question 47 :
8x+10y=90
which gives us possible values of X & Y as (5,5) & (10,1) respectively
Hence total red marbles = 40 or 80
total Black marbles = 50 or 10

@hemant_malhotra 416/400 = 1+r/100
r=4%x/416 =1 +4/100
x =432.64
