Passage / Data
A, B, C are three numbers. Let
@ (A, B) = average of A and B,
/ (A, B) = product of A and B, and
X (A, B) = the result of dividing A by
The sum of A and B is given by
Answer & solution
/(@( A, B), 2)
- B
X(@(A, B), 2)
- C
@(/(A, B), 2)
- D
@(X(A, B), 2)
Solution
Sum of A and B = (Average of A and B) × 2
= /(@(A, B), 2)
∴ Hence, option (a).
