Answer 1

Answer:

$\frac{p \times 12 \times 3 \times 1}{100 \times 2} = 4200$

$p = \frac{4200 \times 100 \times 2}{12 \times 3}$

$\frac{14 \times 100}{6}$

$\frac{7 \times 100}{3}$

$2.33 \times 100$

$233 \: is \: the \: principal$

Answer 2

Answer:

Principal = amount + intrest

Intrest = Rate/100 X time X s.i

Intrest = 12/100 X 3.5 X 4200

Intrest = 1,764

Principal = 4200 + 1764

Principal = 5964
