The best answer is B.
0.04% of 100 00 = (0.04 /100 ) x 100 00 = 4.
Therefore Quantity B is greater.

Replace A with 100 (for example) Y = 130.
Column A = 100 .
Column B = 70% of 130, which is 91 and therefore column A is greater.

The best answer is C.
X = (101 + 102 + 103 + 104 + … + 150).
Y = (201 + 202 + 203 + 204 + … + 250).
Y – X = (201 – 101 ) + ... 150).
Y = (201 + 202 + 203 + 204 + … + 250).
Y – X = (201 – 101 ) + (202 – 102 ) + … + (250 – 150) = 100 + 100 + … + 100 =
100 x 50 = 5,000. And therefore the answer is C.
