Answer:

Step-by-step explanation:

I=840

R=5

T=8

P=?

Now

P=I×100/T×R

=840×100/8×5

=84000/40

=2100

Then

At the rate of 10%

I=PTR/100

=2100×8×10/100

=168000/100

=1680

Again

At the rate of 8%

I=PTR/100

=2100×8×8/100

=134400/100

=1344

Again

At the rate of 9%

I=PTR/100

=2100×8×9/100

=151200/100

=1512

Again

At the rate of 12%

I=PTR/100

=2100×8×12/100

=201600/100

= 2016
