Answer 2

Answer :-

• The simple interest = Rs. 120
• The amount = Rs. 720

Step-by-step explanation:

According the question,

• The simple interest is

We know,

$\underline{\boxed{\sf{Simple \: Interest = \dfrac{PRT}{100}}}}$

Where,

• P = Principal
• T = Time
• R = Rate

Therefore,

$\sf{\longrightarrow \: \dfrac{PRT}{100}}$

$\sf{\longrightarrow \: \dfrac{P \times R \times T}{100}}$

$\sf{\longrightarrow \: \dfrac{600 \times 4 \times 5}{100}}$

$\sf{\longrightarrow \: \dfrac{12000}{100}}$

$\sf{\longrightarrow \: \dfrac{120 \not{0} \not{0}}{1 \not{0} \not{0}}}$

$\sf{\longrightarrow \: 120}$

∴ The simple interest is Rs. 120.

Now,

• The amount

We know,

$\underline{\boxed{\sf{Amount = Simple \: Interest + Principal}}}$

Therefore,

$\sf{\longrightarrow \: Simple \: Interest + Principal}$

$\sf{\longrightarrow \: 120 + 600}$

$\sf{\longrightarrow \: 720}$

∴ The amount is Rs. 720.
