Answer:
R = 0.6
Step-by-step explanation:
The formula to calculate simple interest is:
[tex] \text{Simple Interest} = \frac{{\text{Principal} \times \text{Rate} \times \text{Time}}}{{100}} [/tex]
Given:
Principal (P) = Rs. 80,000
Simple Interest (SI) = Rs. 2,400
Time (T) = 5 years
Let's use the formula to find the rate of interest (R):
[tex] 2400 = \frac{{80000 \times R \times 5}}{{100}} [/tex]
First, multiply 80,000 by 5:
[tex] 80000 \times 5 = 400000 [/tex]
Now, let's solve for R:
[tex] 2400 = \frac{{400000 \times R}}{{100}} [/tex]
To isolate R, multiply both sides by 100:
[tex] 2400 \times 100 = 400000 \times R [/tex]
[tex] 240000 = 400000 \times R [/tex]
Now, solve for R:
[tex] R = \frac{{240000}}{{400000}} [/tex]
[tex] R = 0.6 [/tex]
So, the rate of interest is 0.6 or 0.6%.
Answer:
To calculate the rate of interest, we can use the formula:
Interest = Principal × Rate × Time
Given that the principal (P) is rupees 80,000, the interest (I) is rupees 2,400, and the time (T) is 5 years, we can substitute these values into the formula:
2,400 = 80,000 × Rate × 5
To find the rate, we need to isolate it on one side of the equation.
First, divide both sides of the equation by 80,000 × 5:
2,400 / (80,000 × 5) = Rate
Calculating this expression gives us the value of the rate:
0.006 = Rate
Therefore, the rate of interest is 0.006 or 0.6%.
Another way to calculate the rate is to use the formula:
Rate = (Interest / Principal) × (1 / Time)
Substituting the given values, we get:
Rate = (2,400 / 80,000) × (1 / 5)
Rate = 0.03 × 0.2
Rate = 0.006 or 0.6%
So, the rate of interest for the sum of rupees 80,000 that gives an interest of rupees 2,400 in 5 years is 0.6%.
