Question

A sum of 6,400, accumulated to 9,280, in a certain period. If the rate of simple interest is 9%, find the period.​

Answer 1

Answer:

Time = 5 years

Step-by-step explanation:

P = 6400

A = 9280

I = Amount - P = 9280 - 6400 = 2880

R = 9%

∵ I = ( P × T × R)/100

⇒ T = ( I × 100 ) / ( P × R ) = ( 2880 × 100 )/( 6400 × 9) = 5
