Answer:

here's your answer, grab it

Step-by-step explanation:

GIVEN -

PRINCIPAL = 8500

AMOUNT = 15385

RATE OF INTEREST = 9%

TIME = T

let's calculate the simple interest on the amount.

Amount - principal = SI

15385 - 8500 = 6885

FORMULA -

$si = {principal \times rate \times time} \div 100$

now apply the formula

6885 = (8500 * 9 * T)/100

T = 9

therefore the time is equal to 9 years.

Answer 2

Step-by-step explanation:

• principal =8500
• amount = 15385
• rate of interest = 9 %
• time = ? let, T

interest = amount - principal

interest = 15385-8500

I =6885.

SI = P * R * T /100

6885 = 8500*9* T /100

6885 = 85*9 *T

6885= 765*T

T = 6885/765

so, time will =9 year
