buy price:
b = 1 rupee / 3 lemons = 1/3 rupee/lemon
---
sell price:
s = 2 rupee / 5 lemons = 2/5 rupee/lemon
---
lemons bought:
L = 50 rupee / b
L = 50 rupee / ( 1/3 rupee/lemon )
L = 150 lemons
---
profit eqn:
p = L(s - b)
---
p = L(s - b)
p = 150(2/5 - 1/3)
p = 150(6/15 - 5/15)
p = 150(1/15)
p = (150 lemons) * (1/15 rupee/lemon)
---
profit = 10 rupees
