plz ans fast...​

Answer 1

$A = P×( 1 + \frac{rate}{100} )^n$

$A = 6000×( 1 + \frac{5}{100} )^3$

$A = 6000×( \frac{105}{100} )^3$

$A = 6000 × \frac{105}{100} × \frac{105}{100} × \frac{105}{100}$

$A = \frac{6×21×21×21}{8}$

$A = 6945.75$

Answer 2

The amount is Rs.6945.75 and the compound interest is Rs.945.75 .

Step-by-step explanation:

Given information:

Principal = Rs. 6000

Time = 3 years

Rate of interest = 5% = 0.05

The formula for amount:

$A=P(1+\dfrac{r}{n})^{nt}$

where, P is principal, r is rate of interest, t is number of years and n is number of times interest compounded in a year.

Substitute P=6000, t=3, r=0.05 and n=1 in the above formula.

$A=6000(1+\dfrac{0.05}{1})^{1(3)}$

$A=6000(1.05)^{3}$

$A=6945.75$

Formula for compound interest is

$C.I.=Amount-Principal$

$C.I.=6945.75-6000$

$C.I.=945.75$

Therefore, the amount is Rs.6945.75 and the compound interest is Rs.945.75 .
