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
