1.	at what rate will a borrowed of sum of money charged if it earns 1/4 of itself as interest of 1 year and 9 months
Answer» Given: Interest is 1/4th of the sum of money Time period = 1 YEAR and 9 moths = $1\frac{9}{12} = 1\frac{3}{4} = \frac{7}{4} \: years$ To find: The rate of interest Solution: Let "R" be the rate of interest and "P" be the sum of money Interest received is 1/4th of the sum of money i.e., S.I. = $\frac{P}{4}$ The formula of the simple interest is given by, $S.I. = \frac{PRT}{100}$ Now, we will SUBSTITUTE the given VALUES in the above formula to find the value of R. ∴ $\frac{P}{4} = \frac{P\times R \times \frac{7}{4} }{100}$ cancelling P from both sides ⇒ $\frac{1}{4} = \frac{1\times R \times \frac{7}{4} }{100}$ ⇒ $\frac{100}{4} = 1\times R \times \frac{7}{4}$ ⇒ $100 = 1\times R \times 7$ ⇒ $R = \frac{100}{7}$ ⇒ $\bold{R = 14.28\%}$ Thus, the rate of interest is 14.28%. ------------------------------------------------------------------------------------------------ ALSO VIEW: The interest on a sum of money at the end of 6 1/4 years is 5/16 of the sum itself .

at what rate will a borrowed of sum of money charged if it earns 1/4 of itself as interest of 1 year and 9 months

Answer»

Given:

Interest is 1/4th of the sum of money

Time period = 1 YEAR and 9 moths = $1\frac{9}{12} = 1\frac{3}{4} = \frac{7}{4} \: years$

To find:

The rate of interest

Solution:

Let "R" be the rate of interest and "P" be the sum of money

Interest received is 1/4th of the sum of money i.e., S.I. = $\frac{P}{4}$

The formula of the simple interest is given by,

$S.I. = \frac{PRT}{100}$

Now, we will SUBSTITUTE the given VALUES in the above formula to find the value of R.

∴ $\frac{P}{4} = \frac{P\times R \times \frac{7}{4} }{100}$

cancelling P from both sides

⇒ $\frac{1}{4} = \frac{1\times R \times \frac{7}{4} }{100}$

⇒ $\frac{100}{4} = 1\times R \times \frac{7}{4}$

⇒ $100 = 1\times R \times 7$

⇒ $R = \frac{100}{7}$

⇒ $\bold{R = 14.28\%}$

Thus, the rate of interest is 14.28%.
