plz fast it's quite urgent ​

Answer 1

Answer:

11%

Step-by-step explanation:

3000= 3993(1+i(3) )

1.331=1+3i

0.331=3i ( ingore negative sign )

i=0.11

rate of interest= 11%

Answer 2

In compound interest,

A=P[1+R/100]^n

A is Amount

P is Principal

R is rate of interest

n=time period

given,A=3993,P=3000,n=3yr

hence,

3993=3000[1+R/100]^3

1331=1000[1+R/100]^3

1331/1000=[1+R/100]^3

(11)^3/(10)^3=[1+R/100]^3

11/10=[1+R/100]

(11/10)-1=R/100

1/10=R/100

hence R=10%
