The amount of 120000 should be deposit in X account in the bank as it is giving more amount of compound interest.
As given in the question we have two accounts that is X and Y.
In X account the rate of interest is 8% per annum semi annually compound interest which means 16% per annum for year.
In Y accounts the rate of interest is 12% per annum compound interest for year.
hence, if we deposit the Rs. 120000 in bank with account X then
120000×16%= 19200 [ first year interest]
139200×16%=22272[second-year interest]
the total amount of compound interest = Rs 41472.
now if we deposit in Y account then
120000×12%=14400
134400×12%=16128
the total amount of compound interest =Rs 30528
now we can see that we are getting more interest amounts in X account compared to Y.
hence, depositing the Rs.120000 in account X will be beneficial.

Answer:
(Equation 1)
(Equation 2)
We can substitute Equation 1 into Equation 2 like so:
Subtract x from both sides:
Divide both sides by 2:
.
Substitute into Equation 1 to find y:
Question Three is A, Question Five is B.
From the picture, we have the graph of the linear parent function f(x) = x.
We have the following statements as descriptions of the function:
A. The function is negative when x < 0.
From the graph, we see that the function takes negative values for x < 0. This statement is true.
B. The function is negative when x < 0 and also when x > 0.
The first part of this statement is true, but the second is not because that we see that the function takes positives values for x > 0. So this statement is false.
C. The function is never negative.
If we see the graph, the function is negative when x < 0. So this statement is false.
D. The function is negative when x > 0.
Again, seeing the graph we note that the function takes positive values for x > 0. So this statement is false.
So the only statement that it is true, is option A.
