Best Answer Explained in Below-:

To find the selling price per kg for the mixture, let's first calculate the total cost price (CP) of the pulses Lubana purchased.

For the first 20 kg of pulses: Cost price = 20 kg * Tk. 14.25/kg = Tk. 285

For the next 30 kg of pulses: Cost price = 30 kg * Tk. 11.50/kg = Tk. 345

Total cost price (CP) of both batches = Tk. 285 + Tk. 345 = Tk. 630

Now, Lubana wants to make a profit of 30%. Profit is calculated on the cost price.

Profit = 30% of Tk. 630 = 0.30 * 630 = Tk. 189

So, the selling price (SP) of the mixture should be: SP = CP + Profit = Tk. 630 + Tk. 189 = Tk. 819

Now, to find the selling price per kg, divide the total selling price by the total quantity of pulses (20 kg + 30 kg = 50 kg):

Selling price per kg = Tk. 819 / 50 kg ≈ Tk. 16.38/kg

So, the correct option is 16.38.
