If i and d are integers, what is the value of i?
(1) The remainder when i is divided by (d+2) is the same as when i is divided by d
(2) The quotient when i is divided by (d+2) is d
(1) The remainder when i is divided by (d+2) is the same as when i is divided by d

No numerical value, so in all likelihood it should be E
(1) The remainder when i is divided by (d+2) is the same as when i is divided by d
Whenever i is lesser than d, this will be true. For example : 7 divided by 8 and 10 or for that matter, any number greater than 7 will give 7 as remainder. There will be many more cases that fit in.
Insufficient
(2) The quotient when i is divided by (d+2) is d
many cases possible
d=5, and d+2=7.....i could be 36, 37, 38 etc.
insufficient
Combined
d=5, d+2=7.....i can be 36, 37 etc
d=3, d+2=5.....i can be 16, 17 etc
Insufficient
E

If i and d are integers, what is the value of i?
Stat1: The remainder when i is divided by (d+2) is the same as when i is divided by d
i = 5 and d= 7 or i= 12 and d= 13 Not sufficient to get i.
Stat2: The quotient when i is divided by (d+2) is d
then, i= 1, d= 1 or, i= 36 and d= 5. Not sufficient to get i.
Combining both, still we don't know about i and d. Not sufficient
So, I think E.
