Please explain your approach.

thanks.

Sumithra · Answer

I go with C

Q asks the function of the symbol.

S1:
As 3+2>3 and 3*2>3, the symbol could be + or * so insuff

S2:
As 3*1=3 and 3/1=3 insuff

Together:
We know the symbol is * so suff
Ans C

I went with C as well. However the OA is not C.

Fig · Answer

(A) for me

From 1 3 D 2 > 3 that means D could be the multiplication or the addition operand. By the way, (6+2)+4 = 6+(2+4) and (6*2)*4 = 6*(4*2) SUFF. From 2 3 D 1 = 3 that implies D could be the multiplication or the division operand. (6*2)*4 = 6*(4*2) But, (6/2) / 4 = 3/4 and 6/(4/2) = 6/2 = 3 INSUFF.

Great response FIG.
OA is A.

I misunderstood the question.

mbagal1 · Answer

It seems to be A. The question eq will be true for multiplication or addition (commutative property)

1. This indicates that the delta is addition or multiplication, since for subtraction and division, this will not be true - sufficient
2. This indicates that the delat can be multiplication or division - insuff.
