Answer 2

Answer:

12.5%

Step-by-step explanation:

let the original quantity be 100 gm bought for ₹100

after 20% removal by the shopkeeper we have 80gm which he sold for ₹ 90 (10% deduction for discount)

quantity to be received for ₹90 = 90gm

therefore dal to be added = 90gm - 80gm = 10 gm

% of dal to added can be calculated by dividing the difference by the amount sold by the shopkeeper multiplied by 100

10/80 ×100 = 12.5%
