Question

whatis the principal, if after two years at 13% p.a.simple interest,it amounts to rs.252000

Answer 1

$\huge\red{Answer\: is}$

A = ₹ 252000
R = 13%p.a
T = 2 years
P = ?
Principal = A /(1+ RT/100)
$= \frac{252000}{(1 + \frac{13 \times 2}{100}) } \\ = \frac{252000}{( \frac{63}{50}) } \\ = 252000 \times \frac{50}{63} \\ = 200000$

Hence principal is ₹. 200000

Hope it helps you

Answer 2

Amount=Rs 2,52,000

Rate of interest= 13%

Time= 2 years

Principal =P

→Amount = Simple interest + Principal

→2,52,000- P=Simple interest

As Simple interest= $\frac{\text{principal}\times{\text{time}} \times{\text{rate of interst}}}{100}$

→2,52,000-P=$\frac{P\times13\times2}{100}$

→2,52,00,000 -100 P= 26 P

→100P +26P=2,52,00,000

→126 P=2,52,00,000

→ P=2,00,000

So,Principal =Rs 2,00,000
