Answer :

(D) 3,600​

Given :

  • Principal = 3,000
  • Rate = 10%
  • Time = 2 years

To find :

  • how much money will he get back after 2 years?

Solution :

⇒ Let's find the Simple Interest.

\longrightarrow \sf Simple \: Interest =\dfrac{p \times r \times t}{100}

Here,

  • P = 3,000
  • R = 10
  • T = 2

\longrightarrow \sf Simple \: Interest =\dfrac{p \times r \times t}{100}

\longrightarrow \sf \dfrac{3000 \times 10 \times 2}{100}

\longrightarrow \sf \dfrac{3000 \times 20}{100}

\longrightarrow \sf \dfrac{30 \not0 \not0 \times 20}{1 \not 0 \not 0}

\longrightarrow \sf \dfrac{30  \times 20}{1 }

\longrightarrow \sf \dfrac{600}{1 }

\longrightarrow \sf  600

∴ Simple Interest is 600.

⇒ Let's find the Amount.

\sf \longrightarrow Amount = Principal + Simple \: Interest

\sf \longrightarrow Amount = 3000 + 600

\sf \longrightarrow Amount = 3600

  • Therefore, the Amount is 3,600​.

Question :-

A man deposited * 3,000 for 2 years with simple interest in a bank at the rate of 10 p.c.p.a. How much money will he get back after 2 years?

(A) 300

(B) 600

(C) 3,300

(D) 3,600

Solution :-

We have,

  • Principal = 3000₹
  • Rate = 10%
  • Time = 2 years

Need to find

  • How much money will he get back after 2 years, means we need to find is Amount .

Let's Find the first Simple Interest

  • \sf{SI=\frac{P × N× R}{100}} \\

Now,

\sf:\longmapsto{ \frac{30 \cancel{00 }\times 10 \times 2}{ \cancel{100}} } \\  \\ \sf:\longmapsto{30 \times 10 \times 2} \:  \:  \:  \:  \\  \\ \sf:\longmapsto{600} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We know that,

\sf:\longmapsto{Amount = Simple \:  interest + Principal }

Then,

\sf:\longmapsto{ A =3000 + 600} \\  \\ \sf:\longmapsto{ A =3600} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

Hence,

Option D) is the right answer.
