Let the price of the small box is p and thus, the price of the large box is 2p
Let the weights of chocolates in the small box and the large box are S grams and L grams respectively.
Selling price per gram of chocolate in the large box = 2p/L
Selling price per gram of chocolate in the small box = p/S
Selling price per gram of chocolate in the large box is 12% less than that in the small box
=> Selling price per gram of chocolate in the large box is 88% of that in the small box
=> 2p/L = 88% of p/S
=> 2p/L = 88p/(100S)
=> 2/L = 22/(25S)
=> L/S = 25/11 = 2.27
=> L = 2.27S
=> L is 227% of S
=> L is 127% more than S

STEP 1 : If the selling price per gram of chocolate in the large box is 12% less
Fix Small as 100 & Large as 88 (12% less)
STEP : 2 The large box is sold for twice the price of the small box.
Fix Small as 10000 & Large as 20000 (2 times the amount of small)
STEP 3 : Quantity will be Amount/Price per unit.
L = 227 & S = 100
Quote:
\(\frac{(227-100)}{100}*100 = 127\)%, Answer must be (A)
