Answer 1

Answer:

i) ✮Given:

Principal= ₹350

Time = 2year

Rate = 11%

✮Solution:

$⇒S.I. = \frac{P×R×T}{100}$

$⇒S.I. = \frac{350 \times 11 \times 2}{100} \\ \\ ⇒S.I. = \frac{7700}{100} \\ \\ ⇒S.I. = ₹77$

Therefore, The simple Interest is ₹77.

ii) ✮Given:

Principal= ₹20000

Rate= 17/2%

Time= 9/2 year

✮Solution:

$⇒S.I. = \frac{20000 \times 17 \times 9}{100 \times 2 \times 2} \\ \\ ⇒S.I. = \frac{3060000}{400} \\ \\ ⇒S.I. = ₹7650$

Therefore, The simple Interest is ₹7650.

Answer 2

Answer:

$\large\bf\red{❅\:Solution\:❅}$

Step-by-step explanation:

i) ✮Given:

Principal= ₹350

Time = 2year

Rate = 11%

✮Solution:

⇒S.I. = \frac{P×R×T}{100}⇒S.I.=

100

P×R×T

\begin{gathered}⇒S.I. = \frac{350 \times 11 \times 2}{100} \\ \\ ⇒S.I. = \frac{7700}{100} \\ \\ ⇒S.I. = ₹77\end{gathered}

⇒S.I.=

100

350×11×2

⇒S.I.=

100

7700

⇒S.I.=₹77

Therefore, The simple Interest is ₹77.

ii) ✮Given:

Principal= ₹20000

Rate= 17/2%

Time= 9/2 year

✮Solution:

\begin{gathered}⇒S.I. = \frac{20000 \times 17 \times 9}{100 \times 2 \times 2} \\ \\ ⇒S.I. = \frac{3060000}{400} \\ \\ ⇒S.I. = ₹7650\end{gathered}

⇒S.I.= 100×2×220000×17×9

⇒S.I.=

4003060000

⇒S.I.=₹7650

Therefore, The simple Interest is ₹7650.
