Question

find amount if PRINCIPAL=10800 AND RATE = 12 UPON 1 AND 2 AND TIME=3 YEARS

Answer 1

Formula for amount = Principal + S.I.
= 10800 + S.I.

Now Formula for S.I.=
$\frac{p \times r \times t}{100} \\ = \frac{10800 \times 12.5 \times 3}{100} \\ = 108 \times 12.5 \times 3 \\ = 4050$
Now, Amount = 10800 + 4050.
=14850
