Question

Principal is?, rate of interest is 2.5%, time is 5 years, interest is 2400, amount is?

Answer 1

Step by step explanation:

I=P×R×T/100

2400=P×2.5×5/100

2400=12.5P/100

2400×100=12.5P

2400×100/12.5=P

19200=P

Answer 2

Answer:

the principal is 19200 and the amount is 21600

Step-by-step explanation:

the formula of interest=

$\\i = \frac{p \times n \times r}{100}$

$2400 = \frac{p \times 5 \times 2.5}{100}$

$2400 = \frac{p \times 12.5}{100}$

$\frac{2400 \times 100}{12.5} = p$

$\frac{240000}{12.5} = p$

$19200 = p$

it is an amount formula

$a = p + i$

a=19200+2400

=21600
