1) The average of a, b, c, d, e is c
2) Range of the integers < difference between any two integers in the set



How can the RANGE be less than DIFFERENCE between any two integers in the set

After all RANGE is the difference between the largest and smallest integer of the set. How can it be less ??

Are the distinct positive Integers of Set {a, b, c, d, e} consecutive?

1) The mean of a, b, c, d, e is c
2) Range of the integers = c-a+2

for stmnt1 : we get considering sequence (1,2,3,4,5) yes and (1,2,3,4,6) mean 3.2 ~3 so no

for stmnt 2: if we say range of integers = middle value- first value +2
=> range of integers (e-a) -2=c-a
=> e=c+2

we know relation about e and c but a,b,d are not clear so NO

Combining stmnts we can conclude that a,b,c,d,e have to be consecutive nos.

IMO C should be correct..
