Question

The simple interest on a sum of money at 5% is 748 for 4year Then, find the simple interest on same sum for 5year at 4% ​

Answer 1

Answer:

. Rate, r = 5 %

SI = 48

Time, t = 4 year

Principal, p = ?

We know that,

SI = \frac{p\times r\times t}{100}

100

p×r×t

p = \frac{100\times SI}{r\times t}

r×t

100×SI

p = \frac{100\times 48}{5\times 4}

5×4

100×48

p = 240

Principal is Rs.240/-

ii. p = 240

rate = 4 %

time, t = 5

SI = \frac{p\times r\times t}{100}

100

p×r×t

= \frac{240\times 4\times 5}{100}

100

240×4×5

SI = 48

Simple interest is Rs.48/-

Answer 2

Answer:-

In the first case,

$\small \bf \underline{Given:}$

★★ Simple interest on the given sum of money = ₹748

★★ Rate = 5% per annum

★★ Time = 4 years

$\small \bf \underline{To \: find:}$

We need to find the principal

$\small \bf \underline{Solution:}$

$\small\bf » \: simple \: interest = \frac{principal \times rate \times time}{100}$

Let the principal be p

$\bf \to748 = \frac{p \times 5 \times 4}{100}$

$\bf \to748 = \frac{p \times 20}{100}$

$\bf \to748 = \frac{p \times 2}{10}$

$\bf \to748 = \frac{p}{5}$

$\bf \to \: p = 5 \times 748$

$\bf \to \: p = 3,740$

∴ The principal is ₹3,740

Now, in the second case

$\small \bf \underline{Given:}$

★★ Principal = ₹3, 740

★★ Rate = 4% per annum

★★ Time = 5 years

$\small \bf \underline{To \: find:}$

In this case, we need to find the simple interest

$\small \bf \underline{Solution:}$

$\small\bf » \: simple \: interest = \frac{principal \times rate \times time}{100}$

$\bf= \frac{3740 \times 4 \times 5}{100}$

$\bf= \frac{3740 \times 20}{100}$

$\bf = 374 \times 2$

$\bf= 748$

Answer:- The simple interest is ₹748
