i think:
as given
selling price is: Rs.76
for which profit: 52%
now,
let original cost of the article be 'x'
as per given data: x+(52x/100)=76
i.e (100x+52.x)=7600
152x = 7600
x = 50
so the original cost is Rs.50
now, let the unknown % profit be 'y'
the 2nd selling price is:Rs.75
i.e 50+(50.y/100)=75
(50.y/100)=25
(50.y)=2500
y =(2500/50)
y =50
As per our assumption the percent of profit is y which is 50 therefore if the article is sold for 75 rupees it means that 50% profit is obtained.

pls xcuse me if the answer is wrong as i am a student doing my 2nd B.Tech now.
Thank you
