If 5, 000 earns 86.00 interest in 15 months, how much is the rate of interest?​

Sagot :

0.1146%

Given

  • Principle amount - 5,000
  • Simple Interest - 86.00
  • Rate of interest - ?
  • Time - 15 months

Step by step explanation :

We all know that simple interest is;

  • [tex]SI = \frac{p \times r \times t}{100} [/tex]

First of all, we need to find the formula of rate of interest from the first formula. So,

  • [tex]SI \times 100 = p \times r \times t[/tex]
  • [tex]R = \frac{SI \times 100}{p \times t} [/tex]

Therefore the formula is, rate of a interest is equal to simple interest multiply by 100 over principle amount multiply by time. Lets solve,

  • [tex]R = \frac{86.00 \times 100}{5000 \times 15} [/tex]
  • [tex]R = \frac{43}{375} [/tex]

Approximately, the rate is 0.1146%.

Correction :

Use the formula for finding the simple interest. Then solve it,

  • SI = (5000)(86)(15)/100
  • SI = 85.95
  • SI = aprox. 86
