Find selling price of goods if two salesmen claim to make 25% profit each, one calculating it on cost price while anor on selling price, difference in profits earned being Rs. 100 and selling price being same in both cases?

Let CP's be Rs. 1000 each, their respective SP will be,
1000 == 25%↑ ⇒ 1250 [person calculating profit on the CP]
1000 == 33.33%↑ ⇒ 1333.33 [The person calculating his profit on SP: 25% of SP = 33.33% of CP]
The difference turned out to be = 83.33. This has occured when we have assumed the CP as 1000. But, we are given difference of Rs. 100
So, on comparing,
83.33 = 1000
1 = $$\frac{{1000}}{{83.33}}$$
100 = $$\frac{{1000}}{{83.33}} \times 100$$   = Rs. 1200
