si, new price is 40+2=42

Answer 2

Cost Price of Flour = Rs. 40 per Kg.

Quantity of flour purchased = 2 Kgs.

So the amount paid for the purchase = Rs. 2 x 40 = Rs.80.

Sales Tax on the purchase = 5%.

So the total amount paid including sales tax = Rs. 80 + 5% of 80 = 75 + 5/100 of 80 = 80 + 4 = Rs. 84

Ans; Rs. 84
