Question

Pind the simple interest and the amount when:

1. Principal = 6400, rate = 6% p.a. and time = 2 years.​

Answer 1

Given:

• Principal = Rs. 6400
• Rate = 6% p.a.
• Time = 2 years.

$~~$

To Find:

• Simple interest and amount.

$~~$

Solution:

$~~$

$\longrightarrow { \sf {S.I = \dfrac{P \times R \times T}{100}}} \\ \\ \\ \\ \longrightarrow \sf S.I = \dfrac {64 \cancel{00} \times 6 \times 2}{1 \cancel{00}} \\ \\ \\ \longrightarrow \sf S.I = 64 \times 6 \times 2 \\ \\ \\ \longrightarrow {\underline {\boxed{ \sf{ \pmb{S.I = Rs.768}}}}} \: \pink\star$

$~~$

Now,

$~~$

$\longrightarrow \sf Amount = P + S.I \\ \\ \\ \longrightarrow \sf Amount = 6400 + 768 \\ \\ \\ \longrightarrow {\underline {\boxed{ \sf{ \pmb{Amount = Rs.7168}}}}} ~\pink\star$

$~~$

H E N C E,

• Simple interest = Rs. 768
• Amount = Rs. 7168
