Question 90

Logical Reasoning Puzzles Easy

A, B, C, D, and E are five different integers. When written in ascending order of values, the difference between any two adjacent integers is 8. D is the greatest, and A is the least. B is greater than E but less than C. The sum of the integers is equal to E
The sum of the integers is:

(A) -6
(B) -10
(C) None of these
(D) -8

Correct Solution: Option B

Step-by-step Solution:

The integers A, B, C, D, E are in ascending order: A, E, B, C, D, with adjacent differences of 8. Let A = x. Then:

  • E = x + 8
  • B = E + 8 = x + 16
  • C = B + 8 = x + 24
  • D = C + 8 = x + 32

The sum of all integers equals E:

A + E + B + C + D = E

Substitute the expressions:

x + (x + 8) + (x + 16) + (x + 24) + (x + 32) = x + 8

Simplify: 5x + 80 = x + 8

Solve for x: 4x = -72, so x = -18

Thus, E = x + 8 = -10

The sum of the integers is E, which is -10.

Answer: (b) -10
