Question: Is ∆ = Multiplication or ∆ = Division?

Statemetn 1: 3△1 = 3

Since 3*1 = 3 as well as 3/1 = 3 hence ∆ can be multiplication or division both hence

NOT SUFFICIENT

Statement 2: 0△3 = 0

Since 0*3 = 0 as well as 0/3 = 0 hence ∆ can be multiplication or division both hence

NOT SUFFICIENT

Even after combining ∆ can be both multiplication or division

NOT SUFFICIENT

Answer: Option E

△ -----> can represent / or *

1) 3△1 = 3

3*1 = 3 or 3/1 = 3

Both are possible . Insufficient

2). 0△3 = 0

0/3 = 0 or 0*3 = 0

Both are possible . Insufficient

Together too Insufficent
Hence E

I'm curious what they mean by "ordinary multiplication". Is there some kind of extraordinary multiplication I'm not familiar with? :)

The answer is E, since 3*1 = 3 and 0*3 = 0, and 3/1 = 3 and 0/3 = 0, so we can't tell if the operation is division or multiplication.

If △ represents either ordinary division or ordinary multiplication, which does it represent?

Explanation:

(S1) 3△1 = 3
3*1=3 possible
3/1=3 possible
S1 is insuffficient

(S2) 0△3 = 0
0*3 = 0 possible
0/3 = 0 possible
S2 is insuffficient

Hence E is the correct answer IMO
