Thx In Advance:)​

Answer 1

Step-by-step explanation:

Given

The Simple Interest On A Sum For 5Years Is 2/5 Of The Sum.The Rate Of Percent Per Annum Is?

To Find

• The Rate Of Percent Per Annum?

Solution

Let The Sum Be 'P'

Thus,

$\tt\large\underline{S.I = \frac{2}{5} \times p }$

$\tt\large\underline{ \leadsto \: \frac{2 \times p}{5 } =\frac{pr}{</u></strong><strong><u>2</u></strong><strong><u>0</u></strong><strong><u>} }$

Thus,

R=

2×20

5

$</u></strong><strong><u>R</u></strong><strong><u> </u></strong><strong><u>= \qquad\quad\sf \dfrac{\cancel{40}}{\cancel{5}}$

ThereFore,

{✰}R = 05

$\large{\blue{\bigstar}} \: \: {\underline{\boxed{\blue{\sf{S.I= \frac{P×R×T}{100} }}}}}$

A=P+S.I

$\large{\blue{\bigstar}} \: \: {\underline{\boxed{\green{\sf{P= \frac{S.I×100}{R×T} }}}}}$

Answer 2

Step-by-step explanation:

★Given

The Simple Interest On A Sum For 5Years Is 2/5 Of The Sum.The Rate Of Percent Per Annum Is?

✍︎To Find

$|\footnotesize\text \blue{ Rate \%Of Per Annum?}|$

★Solution

• Let Sum Be 'p'

✪Formula Used

$\large{\bold{\bigstar}} \tt\large\underline\bold{S.I = \frac{P×R×T}{100} }$

$\footnotesize\ \underline \text \blue{ Given That,}$

• T=5
• Sum=$\leadsto \frac{2}{5}$

✪Now,

$\leadsto\quad\tt\large\underline{ \frac{2}{5} \times p = \frac{P \times R}{20} }$

Cut P From Both Of The Sides.

✪So,

$\leadsto\tt\large\underline\bold{R= \frac{2 \times 20}{5} }$

$\leadsto\tt\large\underline \bold{ R = \frac{40}{5} }$

$\leadsto\tt\large\underline\bold{ R = 8\%}$

✪Therefore,

"Rate Percent Of Per Annum=8%"
