A $200 investment at x percent per annum and a $500 investment at y pe...
Given:
- Case-I
- Principal , P = $200
- Rate of interest = x% p.a.
- Principal, P = $500
- Rate of Interest = y% p.a.
- Combined yearly return = 10%
- Principal , P = $200
- Case-II
- Principal, P = $400
- Rate of interest = x% p.a.
- Principal, P = $600
- Rate of Interest = y% p.a.
- Combined yearly return = 9.2%
- Principal, P = $400
To Find: Combined yearly return if $100 each is invested at x% p.a. and y% p.a.?
- Let the combined yearly return be R%
- So, Return on $200 invested at R% p.a. = Return on $100 at x% p.a. + Return on $100 at y% p.a.
Approach:
- For finding the value of R, we need to find the value of x and y.
- We are given two cases in which the principals are invested at x% and y% per annum and we are also given the combined yearly return for both the cases
- The combined yearly return is equal to the sum of the returns of the individual investments
- Writing the combined yearly return equations for each of the case will give us an equation in x and y
- We will solve both the equations to get the value of x and y, which will be used to calculate the yearly return on $100 each invested at x% and y% p.a.
Working out:
- Case-I
- As the combined yearly return is equal to the sum of the returns of individual investments, we can write the following equation
- 2x +5y = 70……………..(1)
2. Case-II
- As the combined yearly return is equal to the sum of the returns of individual investments, we can write the following equation
3. Solving (1) and (2), we have y = 12 and x = 5
4. Hence, combined yearly return on investment of $100 each at x% and y% can be calculated as
4. Hence, combined yearly return on investment of $100 each at x% and y% can be calculated as
