Hint:- In 8 years money from Interest will be come equal to the principal
amount invested. So, money had been doubled in 8 years.

Let the initial amount of money invested will be Rs. x.
Then after 8 years money had become 2x.
Out of Rs. 2x, money from interest will be 2x – initial amount invested = 2x – x = x.
Let the rate of interest be r.

So, now we will use a simple interest formula.
According to Simple Interest (S.I) formula.
\[ \Rightarrow S.I. = \dfrac{{PRT}}{{100}}\]. Where P is principal amount, R is rate of interest and T will be time period.

So, putting the values in the above formula. We will get,
\[ \Rightarrow x = \dfrac{{xr(8)}}{{100}}\]
On solving the above equation. We will get,
\[ \Rightarrow {\text{ }}r{\text{ }} = {\text{ }}\dfrac{{100}}{8}{\text{ }} = {\text{ }}12.5\]

Hence, the rate of interest to double a money in 8 years will be 12.5% per annum.

Note:- Whenever we came up with this type of problem where we are asked to
find rate of interest then first, we will find the interest on principal amount by
subtracting principal amount from the money after 8 years and then we will
assume rate of interest to be r and then apply, Simple Interest formula and
find the required value of rate of interest.

At what rate of simple interest does a sum of money become five times?

Detailed Solution Let the principal be P. ∴ The rate of interest is 25%.

How long will it take a sum of money to become 5 times of itself at 20% pa simple interest?

<br> `rArr 4x = (x xx n xx 20)/(100)` <br> `rArr 4 = (n)/(5) rArr n= 20` <br> `therefore` In 20 years, the sum becomes 5 times itself. <br> Hence, the correct option is (a).

What should be the interest rate for an amount to become 5 times of itself at simple interest in 50 years?

Rate=P×T100×SI=15100×4x=15400=26.

In what time does a sum becomes 5 times at the simple interest at the rate of 5% per annum?

Answer. Hence, the correct answer is 11%.

at what rate percent will a sum of money Doubles itself in 6 years in this question we have been given that consider principal to BP principle is equals to pee so amount is equals to twice of PV know that formula for SI is equals to amount - principle that is topi -3 which is equals to also simple interest is equal to p into our into it upon 130 is equal to p into our in 26 upon hundred Soapy get cancer from this p&r comes out to be 106 that is is equal to 50 by 3 or we can say that 62 by 3%

Solution

The correct option is B 12.5 yearsLet Principal (P)=Rs.a, Time (T)=T years, Rate (R)=8% and Amount (A)=Rs.2a Using formula, A=P+SI, we get, SI=Rs.aTherefore,SI=P×R×T100⇒a×100=a×T×8⇒T=1008=12.5 years

How long will the money double itself at 12.5 per annum?

Time = 8 years. Was this answer helpful?

At what time does money becomes double at a simple interest rate of 12% per annum?

In this problem, it is given that the rate is 12 % per annum and we need to find the time in which the principal amount doubles. The total amount at the end of N years is the sum of simple interest and the principal amount. Hence, the required time is 8 years and 4 months.

How many years does a sum of money becomes three times itself at 12.5% per annum simple interest?

∴ Time is 8 years.

In what time a sum will become triple at 12.5 interest rate per annum?

<br> Given that, <br> Amount `(A)=3 xx ` Principal (P) <br> `therefore P(1+(TR)/(100))=3P` <br> `implies 1+(12T)/(100)=3 implies T=(200)/(12)=16(2)/(3)` years <br> Hence, required time period`=16(2)/(3)` years.

In what time will a sum of money doubles itself at 12 1 2 per annum?

=8 year4 months.

How long will it take for an amount to become 5 times of itself at 20% per annum simple interest?

<br> `rArr 4x = (x xx n xx 20)/(100)` <br> `rArr 4 = (n)/(5) rArr n= 20` <br> `therefore` In 20 years, the sum becomes 5 times itself. <br> Hence, the correct option is (a).

How many years will the sum becomes 5 times itself?

A sum becomes 5 times of itself in 3 years. at compound interest (interest is compounded annually). Let the sum becomes 125 times in n years. ∴ In 9 years it will become 125 times.

How long would take for a sum of money to become 5 times of itself at 20%; per month simple rate of interest?

Let after t years, the sum will become 5 times of itself . Rate = 20 % p.a. So, SI = Rs 5x- x = Rs 4x . = 5/4 years .

How long will it take for an amount to become 5 times of itself at 15% per annum simple interest?

Calculation: Let the sum of money be P. Now, Let the time period be t. ∴ The time is 25 years.

How long will it take for an amount to become 5 times of itself at 5 per annum simple interest?

In what time does a sum becomes 5 times at the simple interest at the rate of 5% per annum?

How long would take for a sum of money to become 5 times of itself at 20 %; per month simple rate of interest?
