The sum of six consecutive even numbers of set-A is 402. What is the sum of another set-B of four consecutive numbers whose lowest number is 15 less than double the lowest number of set- A?

(A) 444

(B) 442

(C) 440

(D) 446

(E) None of these

• The nos. are: 62, 64, 66, 68, 70 and 72.
  15 less than lowest no. = (62 X 2) - 15 = 109
  4 consecutive nos. are = 109, 110, 111, 112
  sum of these 4 nos. = 442
