Answer:

For rate 12%

= p × r × t / 100

= 3200 × 12 × 5 / 100

= 1920

amount = p + s.i

= 3200 + 1920

= 5120 ans ....

For rate 15%

= p × r × t / 100

= 3200 × 15 × 5 / 100

= 2625

Amount = p + s.i

= 3200 + 2625

= 5825 ans....

For rate 20%

= p × r × t / 100

= 3200 × 20 × 5 / 100

= 3200

Amount = p + s.i

= 3200 + 3200

= 6400 ans ...
