Please mark the answer as "The Brainliest answer" if you like it

Step-by-step explanation:

Let Say P purchase price = P

P Seeling price / Q purchase Price = P + (25/100)P = 1.25P

Q Selling Price / R Purchase Price = 1.25P - (15/100)*12.5P

= 1.25P (1-0.15) = 1.25P*0.85 = 1.0625 P

R Selling Price / S Purchase Price = 1.0625 P  + (20/100)*1.0625

= 1.0625P(1+.2) = 1.0625P*1.2 = 1.275 P

1.275 P = 204

P = 204/1.275 =  160

P purchase price = Rs 160
