✔ 最佳答案
let A is SUM OF MOENY IS DEPOSITED A + A x 0.08 x 10/12 = 6400 ( as only 10 months)
A(1+0.08 x 10/12) = 6400
A = 6400 / (1+0.08 x 10/12)
A= 6000
Therefore the money is 6000

The interest rate of 10 months:10/12‧8%
=6/2/3%
Let x be the sum of money deposited.
6/2/3%x=6400
x=96000
The sum of money deposited is 96000.
=6/2/3%
Let x be the sum of money deposited.
6/2/3%x=6400
x=96000
The sum of money deposited is 96000.
