The symbol Ω represents one of the following operations: addition, subtraction, multiplication or division. What is the value of 1 Ω 1?
(1) 2 Ω 2 = 4. This implies that Ω represents addition or multiplication (2+2=4 and 2*2=4). If its addition, then 1 Ω 1 = 1 + 1 = 2 but if its multiplication, then 1 Ω 1 = 1*1 = 1. Not sufficient.
(2) 0 Ω 1 = 0. This implies that Ω represents multiplication or division. In either case 1 Ω 1 = 1. Sufficient.
Answer: B.
Hope it's clear.
