Expert Answer:

Let the cost of article = 100
SP = 120
New CP = 80
If gain is 25% then straight S. straight P equals 125 over 100 cross times 80 equals 100
Difference in selling price = 120 - 100 = 20
If the difference is Rs. 20, C.P. = 100
If the difference is Rs. 60, straight C. straight P. equals 100 over 20 cross times 60 equals Rs. space 300
 

Let the cost of article = x
SP = 1.1x
if
CP = 0.9x
SP = x + 10
P = 10 +0.1x
Then P% = 25%
25 = ((10+0.1x)÷0.9x)×100
x = 80
CP = 80Rs.
