Question

Calculate the interest paid when 4920 is invested at 13% p.a simple interest for eight years​

Answer 1

I'll setup the problem and you can do the calculations

Explanation:

The formula for simple interest:

I = P*r*t

I = interest

P = principle or amount invested

r = interest rate per period (period is a year)

t = number of periods

P = 4920

r = .13

t = 8

Answer 2

Required solution :

Here we have been provided with the principal , rate of interest and time period for which the sum of rupees is invested.

• Principal (P) = Rs.4920
• Rate (r) = 13%
• Time (T) = 8 years

Now here we know that simple Interest is calculated by the formula,

• 
  `\bf{\boxed{\bf{S.I.\: = \: (P * R * T)/(100)}}} \: \red\bigstar`

Here in this formula,

• P is Principal
• R is rate of interest
• T is time

Putting there values in the formula,

`\longrightarrow \: \sf{S.I. \: = \: (4920 * 13 * 8)/(100) }`

`\longrightarrow \: \sf{S.I. \: = \: (492 * 13 * 8)/(10) }`

`\longrightarrow \: \sf{S.I. \: = \: \frac{492 * 13 * \cancel{8}}{ \cancel{10}} }`

`\longrightarrow \: \sf{S.I. \: = \: (492 * 13 * 4)/( 5) }`

`\longrightarrow \: \sf{S.I. \: = \: (492 * 52)/( 5) }`

`\longrightarrow \: \sf{S.I. \: = \: (25584)/( 5) }`

`\longrightarrow \: \sf{S.I. \: = \: \cancel(25584)/( 5) }`

`\longrightarrow \: \orange{\boxed{\bf{S.I. \: = \: 5116.8}}}`

`\underline{\bf{Henceforth, \: interest \: paid \: is \: of \: Rs.5116.8}}`
