1.John deposited $40,000.oo in the bank and earned simple interest of 7% per annum for 2 years. calculate the amount he will receive at the end of the 2 year period.

2. Find the simple interest on $15,000.00 invested for 4 years at 12% per annum.

Interest = Principal * Rate * Time

2800

a man deposited $10000 in his account at a bank 6% simple interest per annum .how much intetrest would he receive on the 10000 afer 9 months

To calculate the amount John will receive at the end of the 2-year period with simple interest, you can use the formula:

Interest = Principal × Rate × Time

1. For John's case, the principal amount (P) is $40,000, the rate (R) is 7% per annum, and the time (T) is 2 years.
Plugging these values into the formula, we get:

Interest = $40,000 × 0.07 × 2 = $5,600

2. To find the simple interest on $15,000 invested for 4 years at 12% per annum, we can use the same formula.

Principal amount (P) = $15,000
Rate (R) = 12% per annum
Time (T) = 4 years

Plugging these values into the formula, we get:

Interest = $15,000 × 0.12 × 4 = $7,200.

Thus, John will receive $5,600 at the end of the 2-year period, and the simple interest on the $15,000 invested for 4 years at 12% per annum will be $7,200.
