22. Contribution Margin Ratio is calculated by dividing the contribution margin by sales. The formula to calculate the contribution margin ratio is as follows:
Contribution margin ratio = (Selling price per unit - Variable cost per unit) / Selling price per unit
Selling price per unit = $200
Variable cost per unit = $75
Contribution margin = Selling price per unit - Variable cost per unit
Contribution margin = $200 - $75
Contribution margin = $125
Contribution margin ratio = ($125 / $200) × 100
Contribution margin ratio = 62.5%
Therefore, the Contribution margin ratio is 62.5%.34.
We are given, Principal (P) = $1000
Rate of Interest (r) = 5% Time period (t) = ?
We need to find the time period (t).
We know that
Simple Interest (SI) = P × r × t / 100
Also,
S.I. = $1300 - $1000 = $300
We will substitute the values of P, r, and SI in the above formula and then we will calculate t.
Thus,300 = 1000 × 5 × t / 1003 = t / 20t = 60/3t = 20 years
Therefore, $1000 will become $1300 at a rate of 5% in 20 years.49.
We are given,
Principal (P) = $40,000 Rate of Interest (r) = 7% Time period (t) = 2 years
We need to find the interest earned (I).
We know that
Simple Interest (SI) = P × r × t / 100
Let's substitute the values in the above formula.
I = P × r × t / 100I = $40,000 × 7 × 2 / 100I = $5,600
Therefore, the interest earned at the end of the period is $5,600.51.
Let the deposit amount be 'P'.
We are given,
Interest rate = 3.6% p.a. Interest earned = $75
We need to find the deposit amount (P).
We know that
Simple Interest (SI) = P × r × t / 100
Where r = Rate of Interest
t = Time period
As the time period is given as 6 months, we need to convert it to years.
Thus, t = 6/12 years = 1/2 years
Let's substitute the values in the above formula and calculate the deposit amount (P).75 = P × 3.6 × 1/100
P = $20,833.33
Therefore, the customer deposited $20,833.33 in the term deposit.
