By the rate and time....

You can use a simple interest formula for finding the principle amount. It is as follows:

P= I/rt

where

p is the principal amount

I is the interest amount

r is the rate of interest

T is the time for investment

P= I/rt

where

p is the principal amount

I is the interest amount

r is the rate of interest

T is the time for investment

P=?, T=5years, R=5%, A=5550

Please solve it & also advice me how you can solve it By taking these formulas

I=p*r*t & A=P+I

Please solve it & also advice me how you can solve it By taking these formulas

I=p*r*t & A=P+I

Please solve it & also advice me how you can solve it By taking these formulas

I=p*r*t & A=P+I

I x r x t ex: I = 680$ p = ? R = 2% t = 4 years 680 x .02 x 4 = 896 and 896 is your answer! Hope I helped!

A = P(1+rt) if the interest is not compounded.

A = total amount; P = principal amount; r = interest rate for a period; t = number of periods

P = A/(1+rt) (divide both sides by (1+rt))

Example

An amount of $1200 is the balance after 2 years at an interest rate of 10%.

P = $1200/(1+.10*2) = $1200/(1.20) = $1000

_____

If the interest is compounded n times per period,

P = A/(1+r/n)

A = total amount; P = principal amount; r = interest rate for a period; t = number of periods

P = A/(1+rt) (divide both sides by (1+rt))

Example

An amount of $1200 is the balance after 2 years at an interest rate of 10%.

P = $1200/(1+.10*2) = $1200/(1.20) = $1000

_____

If the interest is compounded n times per period,

P = A/(1+r/n)
