Question

1. Find the simple interest and amount in each of the
following:
(a) P = $1800
R= = 5%
T= 1 year
(b)P = $2600
R = 12%
T = 3 years
(c) P = $3125
R = 15%
T = 73 days
(d) P = $5660
R = 11%
T= 9 months
(e) P = $180
R = 3%
T = 11/4 year
2. What sum would yield an interest of $36 in 3 years
at 3% p.a.?
3. At what rate per cent per annum will $250 amount
to $330 in 4 years?
4. At what rate per cent per annum will $400 yield an
interest of $78 in 1/2 years ?
5. In what time will $400 amount to $512 if the
simple interest is the calculated at 14% p.a.?​
