A, B, C, D and E are five different integers. When written in the ascending order of values, the difference between any two adjacent integers is 4. D is the greatest and A the least. B is greater than E but less than C. The sum of the integers is equal to E.

1. The sum of A and B is:
a] -10
b] -15
c] 10
d] None of these

2. The greatest number has the value:
a] 9
b] -5
c] 3
d] 7

3. The sum of the integers is:
a] 25
b] -6
c] -15
d] None of These

4. The product of the integers is:
a] -945
b] 945
c] 915
d] None of these

  A,B,C,D,E
  from given condn
  
  A < E < B < C < D
  
  these are in AP with cd = 4
  
  A=x , E=(x+4), B=(x+8), C=(x+12), D=(x+16)
  
  also, A+B+C+D+E = E
  => A+B+C+D = 0
  => X+(X+8)+(X+12)+(X+16)= 0
  => 4X +36 = 0
  => X = -9
  
  SO, A=-9 , E=-5 , B=-1 , C=3 , D=7
  
  (1) sum of A and B = -9+(-1) = -10
  (2) greatest number = D = 7
  (3) sum of the integers = A+B+C+D+E = -5
  (4) product of the integers =ABCDE = (-9)*(-5)*(-1)*(3)*(7)= -945

• order of numbers is
  A,E,B,C,D
  sum of numbers is equal to E and the diff be numbrs is 4 so
  A+E+B+C+D: (E-4)+E+(E+4)+(E+8)+(E+12)=E
  4E=-20
  E=-5
  
  soo ans are
  1) (A)
  2) (D)
  3) (D)
  4) (A)

• increasing order A-(-9), E(-5), B(-1), C(3), D(7).
  1) -10
  2) -7
  3) -5 ,NONE OF THESSE
  4) -945

• from the given question all numbers can not be positive some have to be negative to satisfy the condition.
  and from the given question the asc order is A E B C D
  now try out the options in the 2nd bit rather than a straight forward way.
  so the greatest no would be 7 from trial and error
  from this D=7, C= 3, B =-1, E = 5, A = -9 satisfy the condition hence we can answer the above qsns
