Statement 1:
Insufficient as for the diamond and spade can take on multiple values. E.g. Diamond = 1,Spade = 7, etc.

Statement 2:
Spade can only take on the value of 1. Therefore, Diamond = 7.
Sufficient.

I say cards are not my forte :dazed

I will be replacing them with a(club), b(diamond) and c(spade)

given they are different, positive digits.

if a-b = c, what is b =??

from 1) a =8, no information about b and c

from 2) b =7 c

now c = 1, 2, 3, b will be 7,14,21

which when put back in a-b =c, can give you different values for a, like 8,16,24

Now lets combine

a is fixed, a-b cannot be -ive

Only one value satisfies the above expression, making b = 7

C

b can only be a single digit, not two digit numbers as you have noted.

That's why i said before,i dont like cards :-D

You are absolutely correct, general definition of a digit is

values comprising of 0,1,2,3,4,5,6,7,8,9

Thank you.
