Answer is B- you might begin to visualize the story.
100 + 100 * 10/100 = 110
NOW 110 INCREASES BY 10 %, 110 + 110*10/100 = 110+ 11 = 121
INCREASE OF 20 % = 100 + 100*20/100= 100+20 = 120
SO IT IS NOT SAME
Since she used 12 marshmallows and 8 graham crackers to make the four s'mores, you can figure out that she used 2 graham crackers per s'more (8/4) and 3 marshmallows (12/4).
To keep the same amount of materials per s'more you would need 2 x 3 = 6 (so 6 graham crackers) and 3 x 3 = 9 ( so 9 marshmallows).
