Answer:
The principal on the was $2000.
Step-by-step explanation:
We know that,
[tex]i=\dfrac{P\cdot r\cdot t}{100}[/tex]
where,
i = interest,
P = principal,
r = rate of interest,
t = time.
Putting the given values,
[tex]\Rightarrow 840=\dfrac{P\cdot 6\cdot 7}{100}[/tex]
[tex]\Rightarrow P=\dfrac{840\cdot 100}{6\cdot 7}=\dfrac{84000}{42}=\$2000[/tex]
Therefore, the principal on the was $2000.
