Answer :-

  • Hari paid Rs 468 to his friend after eight months.

To find :-

  • The amount Hari paid to his friend.

Solution :-

  • Here, the principal, rate and time are given to us. We have to find the total amount Hari paid to his friend after 8 months. For this, we first have to find the simple interest on the principal!

We know that :-

  \bigstar \:  \underline{ \boxed{\sf SI =  \dfrac{Principal \times Rate \times Time}{100}}}

Where,

  • SI = Simple Interest.

Here,

  • Principal = Rs 450.
  • Rate = 6% per annum.
  • Time = 8 months = 8/12 years.

Therefore,

 \longmapsto \rm SI =  \dfrac{450 \times 6 \times 8}{100 \times 12}

Cancelling the zeroes,

 \rm \longmapsto SI =  \dfrac{45 \times 6 \times 8}{10 \times 12}

Cancelling the numbers,

  \rm\longmapsto SI =  \dfrac{9 \times 1 \times 2}{1 \times 1}

 \rm \longmapsto SI =  \dfrac{18}{1}

 \rm \longmapsto SI = Rs \: 18

---------------------------------------

  • Now let's find the amount Hari paid to his friend!

We know that :-

  \bigstar \:  \underline{ \boxed{\sf Amount = Principal + SI}}

Where,

  • SI = Simple Interest.

Here,

  • Principal = Rs 450.
  • Simple Interest = Rs 18.

Therefore,

 \bf Amount = 450 + 18

 \bf Amount = Rs \: 468

 \\

Hence :-

  • Hari paid Rs 468 to his friend.
