Answer 1

Answer:

7500

Step-by-step explanation:

FORMULA TO BE USED

SI= PRT/100

AMMOUNT OR TOTAL DEPT= P + SI

WHERE:-

P:- PRINCIPAL AMMOUNT

R:-RATE OF INTEREST

T:- TIME TILL AMMOUNT IS BORROWED

SI:- SIMPLE INTEREST

1) Given values

R:-8%

T:-4 YRS

TOTAL DEPT:-9900

2) we know that

SI= PRT/100

putting all the values

SI= P*4*8/100

SI= 8P/25

3) we know that

TOTAL DEPT= P+SI

putting the value of SI from STEP-2 and total DEPT from step 1

9900= P+8P/25

9900= 33P/25

25*9900/33=P

P=7500

HENCE,

AMMOUNT TAKEN WAS=7500
