Question

R=15%,T=3years,simple interest=1200,Find principle and amount​

Answer 1

Answer:

SI = PRT/100

$1200 = \frac{p \times 15 \times 3}{100} \\ \\ 120000 = p \times 15 \times 3 \\ \\ p = \frac{120000}{15 \times 3} \\ \\ p = 1600$

AMOUNT = PRINCIPAL + SI

= 1200 + 1600

AMOUNT = 2800

Answer 2

Answer:

$\\ →SI = \frac{PRT}{100}$

$\\→1200 = \frac{P×15×3}{100}$

$\\→ 1200×100 = P×15×3$

$\\→120000 = P×15×3$

$\\→ P = \frac{120000}{15×3}$

$→P = 1600$

$Amount = Princpal + SI$

$→1200 + 1600 = 2800$
