Question

Find the sum which will amount to 20808 at
the rate of 2% p.a. after 2 years.​

Answer 1

Step-by-step explanation:

Here A = 20,808

r = 2%

t = 2 years

Let the principal is P

Then, S.I = Prt/100

$= \frac{p \times 2 \times 2}{100}$

$= \frac{p}{25}$

Now, A = P + S.I

=> 20,808 = P + P/25

$= > 20808 = \frac{25p + p}{25}$

$= > 20808 = \frac{26p}{25}$

$= > p = 20808 \times \frac{25}{26}$

$= > p = 20007.69$

Therefore the sum of money is Rs. 20,007.69

Answer 2

Answer:

20,000

Step-by-step explanation:

A=20808 R= 2% T= 2 year

A = P ( 1× R / 100 ) n

20808 = P ( 102 /100)2

P = 20808 × 102× 102 / 100× 100

P = 20808 × 10404 / 10,000

P = 2× 10,000

P = 20,000
