Let's assume that Shanti bought 7 lemons for Rs. 26.

The cost price of each lemon = 26/7

Shanti sold 6 lemons for Rs. 77.

The selling price of each lemon = 77/6

Profit on 6 lemons = Selling price of 6 lemons - Cost price of 7 lemons

Profit on 6 lemons = (77/6) - (26/7)

Profit on 6 lemons = 71/42

We know that profit percentage is given by:

Profit percentage = (Profit/Cost price) * 100

Substituting the values, we get:

Profit percentage = [(71/42)/(26/7)] * 100

Profit percentage = 150%

Therefore, Shanti's profit percentage is 150%. This means that she made a profit of 150% on her investment.
