If the symbol ▼ represents a sequence of any two (unique or repeated) operations from either addition, subtraction, multiplication, or division, i.e. x ▼ y = (x & y) # y where operators & and # can be either addition, subtraction, multiplication, or division, e.g. two possibilities of x ▼ y can be (x + y) + y and (x +y ) / y, what is the value of 16 ▼ 2?
(1) 18 ▼ 3 = 3
(2) 8 ▼ 2 = 2
(1) 18 ▼ 3 = 3

From statement (1), upon examining the possible signs for (18&3)#3 = 3
(&,#) can be only (/,-) , so 16 ▼ 2 will be definitely 6 --> sufficient
From statement (2), upon examining the possible signs for (18&2)#2 = 2
(&,#) can be (/,-) or (/,/), so 16 ▼ 2 can be 6 or 4 --> insufficient

with the given expression
1) 18 ▼ 3 = 3 explanation
it could be
18/3 - 3 = 3
no other way
Hence a sufficient
2) 8 ▼ 2 = 2
it could be 8/2 / 2 i.e 4/2 = 2
or other can be 8/2 -2 = 4-2 = 2
two possible operations.
Hence not sufficient.
thus A
