Answer 1

Answer:

Principal: The money which we deposit in or the lower from the bank or the money learned called the principal.

Rate of interest: The interest paid on $ 100 for one year is called the rate per cent per year or rate per cent per annum.

Time: The period of time for which the money is lent or invested.

Interest: Additional money paid by the borrowed to the lender for using the money is called interest.

Simple Interest: If the interest is calculated uniformly on the original principal throughout the lone period, it is called simple interest.

Amount: The total money paid back to the lender is called the amount.S.I = (P × R × T)/100

R = (S.I × 100)/(P × T)

P = (S.I × 100)/(R × T)

T = (S.I × 100)/(P × R)

If the denotes the amount, then A = P + S.I

Answer 2

Answer:

sI = p*r*t/100

si=p*4*5/100

= p/5

amount = p+ si

1200. = p+p/5

1200 = 6p/5

1200*5/6. = p

1000. = principal

amount = 1000+si

1200 -1000 = si

200. = si
