Question

What amount should be invested at 4% for three years to get ₹19510 as compound interest?

Answer 1

Answer:Rs 21946.09

Step-by-step explanation:

principal = 19510Rs

Rate = 4%

time =3 year

Amount = P(1+R/100)^T

19510(1+4/100)^3

19510(1+1/25)^3

19510*(26/25)*(26/25)*(26/25)

= Rs 21946.09

Here is your answer
Principal = P
A = Rs 19510
R = 4%
T = 3 years

As we know that
A = P(1+R/100)^t
$19510 = p(1 + \frac{4}{100} ) {}^{3} \\ 19510 = p(1 + \frac{1}{25}) {}^{3} \\ 19510 = p( \frac{26}{25} ) {}^{3} \\ p = \frac{19510 \times 25 \times 25 \times 25}{26 \times 26 \times 26} \\ p = 17344.31 \\ p = 17344$
Therefore he invested Rs 17344
