Rs.285 is ur answer .

$\huge\underline{S}\underline{o}\underline{l}\underline{u}\underline{t}\underline{i}\underline{o}\underline{n}↓$

Given,

• Amount = Rs. 364.80

• Rate = 3.5%

• Time = 8yrs.

• Principal = ?

Since,

Amount = $P(1 + \frac{rt}{100})$

364.80⠀= $P(1 + \frac{3.5 \times 8}{100})$

364.80⠀= $P(1 + \frac{28}{100})$

364.80⠀= $P(\frac{128}{100})$

$\frac{364.80 \times 100}{128}$⠀= P

285 = Principal Ans.

Answer 2

Answer:

$285 \: \: \: is \: the \: answer$

Step-by-step explanation:

GIVEN,

Amount = Rs. 364.80

Rate (R). = 3.5%

Time ( T) = 8 years

Principal =?

Since,

Formula for finding principal is

$amount \: = P(1 + \frac{R \times T}{100} )$

$364.80 = P(1 + \frac{3.5 \times 8}{100} )$

$364.80 = P(1 + \frac{28}{100} )$

$364.80 = P( \frac{128}{100} )$

$\frac{364.80 \times 100}{128} =P$

$285 = P$

Principal = 285
