Simple intrest = 829.50

Rate of intrest - 10 °/•

Time = 3 years

Principal = ?

So how to find the principal ?

Explanation :-

$\frac{ PTR \: }{100} \\ 829.50 = p \times 3 \times \frac{10}{100} \\ p = 829.50 \div \frac{3}{10} \\ p = 829.50 \times \frac{10}{3} \\p = 276.50 \times 10 \\ p = 2765$

Principal = 2765
