Answer 1

Answer:

the sum is rs. 20007.69

Step-by-step explanation:

let sum be s

we know that amount  = sum + interest

interest = sum * rate of interest * time ( in years )

= s * 2/100 * 2

= s/25

=> s + s/25 = 20808

=>  ( 25s + s ) / 25 = 20808

=> 25s + s = 20808 * 25 = 520200

=> 26s = 520200

=> s = 520200 / 26

= 20007.69
