Set A contains all the even numbers between 2 and 50 inclusive. Set B contains all the even numbers between 102 and 150 inclusive. What is the difference between the sum of elements of set B and the sum of the elements of set A?  Choose the most appropriate option:
A) 2500 B) 5050 C) 11325 D) 6275 E) 2550
SET A: {2, 4, 6, 8,...., 50}. Set of first 25 consecutive positive even numbers.   SET B: {102, 104, 106,....., 150}. Another set of 25 consecutive even numbers starting from 102.   Difference between 1st term of set A and that of set B is 100. Difference between 2nd term of set A and that of set B is 100.   Each term in set B is 100 more than the corresponding term in set A.   So sum of the differences of all the terms is (100 + 100 + 100 + ....) = 25 * 100=
