is greater than that of
.
Step-by-step explanation:
Given:
The growth rates of both bank accounts are given as:

Now, as per question, we need to find the value of 'x' when the value of
. Or,

Now, we can do this by checking the values of 'x' by hit and trial method.
Let
. The inequality becomes:

Let
. The inequality becomes:

Let
. The inequality becomes:

Let
. The inequality becomes:

Therefore, the value of 'x' for which
is 4.
So, from the fourth month onwards, the balance in
becomes greater than
.
The graphical solution is shown below to support the same.
From the graph, we can conclude that after the 'x' value equals 3.4, the graph of
lies above of
. Hence,
for
