The correct option is
B
6
Suppose, one green chip is equivalent to
+
1.
Now, to find the value of
(
2
+
4
)
, we have to add
2
and
4
which is equivalent of adding
2
and
4
green chips (as one green chip is equivalent to
+
1
).
Addition of
2
and
4
green chips results in
6
green chips as depicted in the following.
And,
6
green chips are equivalent to
+
1
+
1
+
1
+
1
+
1
+
1
=

6
=

.
Therefore,
2

4
=
