ST1: can be either multiplication or division
ST2: can be either multiplication or subtraction

Combined-@ is definitely multiplication

hence C

In statement 2 , for either case ( substraction or multiplication) u get 1/3@1/4 = 1/12 so B is sufficient. It's a tricky question.

Stmt 1: Not sufficient - can be multiplication or Division. If you test these on the prompt you will get 1/12 with multiplication and 4/3 with division - so NS

Stmt 2: Sufficient - can be multiplication or subtraction. If you test both on the prompt you will get 1/12 for each, therefore it is sufficient since you will receive one unique answer no matter what the operation is. Note that the question asks specifically what the answer would be.

TLDR: Answer is B

Answer should be B.
\(1/3@1/4\)
1/3 - 1/4 = 1/12
1/3*1/4 = 1/12
So both multiplication and subtraction gives the same answer for the stem. We need to find out whether any of the 2 statement gives the same answer

from 1.
1*1 = 1
1/1 = 1
so 1/3 -1/4 = 1/12
(1/3) / (1/4) = 4/3
different answer clearly Not sufficient.

From 2.
1/2 - 1/3 = 1/6
1/2 * 1/3 = 1/6
both answer gives same, which is similar the operation used in the question stem.
So sufficient.

Answer B

1) \(1@1=1\)
2) \(\frac{1}{2}@\frac{1}{3}=\frac{1}{6}\)

self made : from a similar but still different Q

Statement 1: can be multiplication or division yields different values for \(\frac{1}{3}@\frac{1}{4}\)

Statement 2: can be multiplication or subtraction yields same values for \(\frac{1}{3}@\frac{1}{4}\)

Therefore B is Answer
