Given: x is 40 percent of y
So, we can write x = (40/100)(y) = 0.4y
Now replace x with 0.4y in Quantity B to get:
QUANTITY A: y
QUANTITY B: 3(0.4y)
Simplify:
QUANTITY A: y
QUANTITY B: 1.2y
At this point, you may already see that quantity B is greater.
Nevertheless, we can add the next step to be 100% certain.
Since we're told y is POSITIVE, we can safely divide both quantities by y to get:
Simplify:
QUANTITY A: 1
QUANTITY B: 1.2
Answer:B

Let take y = 100
x = 40*100/100 = 40
option B = 120 and > A
Hence correct ans is B
x = 40*100/100 = 40
option B = 120 and > A
Hence correct ans is B
