The time it takes for a man to get Rs 50,000 is 5 years and 4 months i.e., t = 5.36 years. Using the compound interest formula the required value is calculated.
<h3>What is the formula for calculating compound interest?</h3>
The formula for calculating the compound interest is
A = P(1 + r)^t
Where
A = total amount at the end of the tenure
P = Initial amount
r = Interest rate
t = time(years)
<h3>Calculation:</h3>
It is given that,
A man invested Rs 30,000; the rate of interest r = 10% and he gets a total amount of Rs 50,000 after some time 't'.
Then,
A = P(1 + r)^t
⇒ 50000 = 30000(1 + 0.1)^t
⇒ (1.1)^t = 50000/30000
⇒ (1.1)^t = 5/3 =1.67
Applying logarithm on both sides,
log(1.1)^t = log(1.67)
⇒ t (log(1.1) = log(1.67)
⇒ t = log(1.67)/log(1.1)
∴ t = 5.38 years
Therefore, it takes 5 years and 4 months to get the amount of Rs 50,000 for the initial investment of Rs 30,000.

Answer:
A. 6.466
B. 6
C. 5
D. 30 nominations
Step-by-step explanation:
A. The mean is all of the numbers added together, and divided by how many numbers there are, so take all of the numbers, which end up being added up to 97, and then divide by 15, because that´s how many numbers there are, you end up getting 6.46666 and you round it to 6.466
B. The median is when you take all of the numbers and put them into order, and then find the number in the exact middle of all of the numbers, so the numbers were 4 5 5 5 5 5 5 6 6 7 7 8 8 9 12, the middle number was 6
C. The mode is the number that appears the most, and that would be 5
D. The most reccuring number is 5, and if you take that and multiply it by how many times it is shown, 6, you get 30

The answer for 18 is 175 (use khan academy)
Step-by-step explanation: base1 + base2 (times) height divided by 2
The first integer (x) is equal to the consecutive even integers, x+2, x+4.
x = (x+2) + (x+4)
x = 2x + 6
x - 6 = 2x
x = -6 (First integer)
+2
-4 (Second integer)
+4
-2 (Third integer)
Integers: -6, -4, -2
Equation: x = (x+2) + (x+4)
