Direction (1-5) :

12*3=36

36*2.5=90

90*2=180

180*1.5=270

270*1=270

270*0.5=135

Direction (6-10) :

Let the MP=Rs.100x

SP =100x*(80/100) =80x

80x=CP*(125/100)

CP = 64x

Required percentage= [(100x – 64x)/100x]*100=36%

Let the MP of D=100x

MP of C = (4/5)*100x=80x

Ram=80x*90/100 + 100x*80/100 = 72x+80x=152x

Sunil=80x*80/100 + 100x*90/100 = 64x+90x=154x

Required ratio=152x: 154=76: 77

MP of the article E = 2x

MP of the article D = x

2x*85/100 – x*80/100 = 900

90x = 90000

X = Rs. 1000

MP of article E = 2*(1000) = Rs. 2000

CP of article B = x

MP of article B = y

SP of article B = y*75/100 = 3y/4

MP of article A = (150/100)*y = 3y/2

SP of article A = (3y/2)*(80/100) = 6y/5

6y/5 – 3y/4 = 1800

24y – 15y = 1800*20

Y = Rs. 4000

According to the question,

4000*(75/100) = x*(120/100)

X = Rs. 2500

CP of D = x

CP of C = (250/100)*x = 5x/4

MP of C = (5x/4)*(150/100) = 15x/8

MP of D = x*(120/100) = 6x/5

Required ratio= [(15x/8)*(90/100)] : [(6x/5)*(80/100)] = 225 : 128
