Pramod:
Let P be the actual price and S be the selling price. Profit is S - P. Raju (a beginner in business, poor fellow!) calculated his profit percentage as (S-P)/S x 100, which is given to us as equal to 100/3. Hence (S-P)/S = 1/3.
(S-P)/S = 1 - P/S = 1/3
P/S = 2/3
S = (3/2)P
S- P = (1/2)P
Profit, as a percentage of P, is [(1/2)P/P]x100 = 50 per cent!!!
