Answer 1

$\begin{gathered} \\ \Large{\bf{\green{\underline{AnSwEr\::}}}} \\ \end{gathered}$

• Interest for 24 months = ₹ 400

$\begin{gathered} \\ \Large{\bf{\red{\underline{GiVeN\::}}}} \\ \end{gathered}$

• Principal = ₹ 4,000.

• Rate = 5 %.

• Time = 24 months = 2 years.

$\begin{gathered} \\ \Large{\bf{\purple{\underline{To \: FiNd\::}}}} \\ \end{gathered}$

• The interest for 24 months means 2 years.

$\begin{gathered} \\ \Large{\bf{\pink{\underline{SoLuTiOn\::}}}} \\ \end{gathered}$

$\large{ \red{ \sf{ \underline{ \boxed{ \sf{ : \implies \: \: \: interest \: = \: \frac{ptr}{100} \: \: \: \: \: \: \: \: \: \: \: }}}}}}$

$\sf \: \implies \: interest \: = \: \frac{4000 \times 2 \times 5}{100} \: \: \: \\ \\ \sf \: \implies \: interest \: = \: \dfrac{40 \: { \cancel{00} \times 2 \times 5}}{{ \cancel{100}}} \\ \\ \sf \: \implies \: interest \: = \: 40 \times 2 \times 5 \: \: \: \: \: \: \: \\ \\ \sf \: \implies \: \red{interest \: = \: 400 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }$

Answer 2

Step-by-step explanation:

$\huge\star\sf\fbox \red{Question} : -$

A sum of Rs 4000 is lent at the rate of 5% per annum. Find the interest at the end of 24 months.

$\huge\star\sf\fbox \green{GiveN} ::-$

Principal = ₹4000

Time = 2year OR 24months

Rate = 5%

To Find ::-

Interest of 2years.

$\star\sf\underline \purple{Formula} ::-$

$\sf \red{\frac{PTR }{100} }$

$\huge\star\sf\fbox \pink{Required Solution} ::-$

$\longrightarrow \frac{ \cancel \red{4000} \times 5 \times 2}{ \cancel \red{100}} \\ \longrightarrow40 \times 2 \times 5 \\ \huge \longrightarrow \sf \fbox \orange{400}$

$\green\therefore\sf \purple{ \: Interest \: of \: 2 year = }\huge \blue{₹400}$
