The symbol ∆ denotes one of the four arithmetic operations:addition,subtraction,multiplication,or division,If 6∆3≤ 3 ,which of the following must be true ?
Since 6∆3≤ 3
6*3 = 18 >3
6+3=9>3
6/3 = 2 <=3
6-3 =3 <=3
Therefore, operator ∆ denotes / or - operations
I. 2∆2 = 0
2/2=1
2-2=0
NOT NECESSARILY TRUE
II. 2∆2 = 1
2/2=1
2-2=0
NOT NECESSARILY TRUE
III. 4∆2 = 2
4/2=2
4-2=2
4∆2 = 2 regardless of the operator / or -
MUST BE TRUE
IMO C
