□ +△ ___ ★ In the addition problem above, each of the symbols □, △, and ★ represents a positive digit. If □ < △,what is the value of △ ? Statement 1: ★ = 4 Given □ < △, only one possibility □ = 1 and △ = 3  Sufficient Statement 2: □ = 1 △ can be {2,3,4,5,6,7,8}  Insufficient Answer A

Data to be derived from question. All the 3 figures are positive digit. Hence these numbers can be only between 1&9 (inclusive) and will be distinct as one as the square is smaller than triangle, which means both are different digits and adding two different +VE digits will give you a 3rd digit that is different from previous 2.
S(1): *=4. The possible combinations are 3,1 1,3 & 2,2. Since we know triangle is bigger than square it only leaves us with 1,3. Hence Suff.
S(2) Square=1. Which means triangle can be any number between 28 to satisfy above conditions. Hence N.S.
THus answer is A.

Where in the problem does it state that the number has to be an integer? All it says is that the three symbols correspond to a positive digit so the Triangle and Square can be any infinite number of combinations 1 (since the triangle is bigger) therefore the answer must be C.

There are only 10 digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. We are told that symbols represent positive digits, so they can be 1, 2, 3, 4, 5, 6, 7, 8, or 9.
