<u>Answer-</u>
<em>He purchased a rope of </em><em>48 ft</em><em>.</em>
<u>Solution-</u>
Let us assume the length of the rope he had originally purchased was x ft.
He used one-fourth of the x to make a bow, so the rope he used was
The amount he left with was,
Then he used one-third of the remaining to tie up a roll of carpet, so the rope he used was
Then he left with 24 ft of rope.
∵ The total amount = Amount used + Amount left
Hence,
Therefore, he purchased a rope of 48 ft.
We need to calculate 10 1/8 / 1 3/4
= 81/8 * 4/7 = 81/14 = 5.8
this is > 5 so he does have enough wood to make 5 shelves
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:
3^10
Step-by-step explanation:
Because the rules of index
3^4 = 3*3*3*3
3^6 = 3*3*3*3*3*3
(3^4)(3^6)=
3*3*3*3*3*3*3*3*3*3 = 3^10
