the compound interest earned by sunil on a certain amount at the end of two years at the rate of 5 % p . a . was rs . 246 . find the total amount that sunil got back at the end of two years in the form of principal plus interest earned .
"let the sum be rs . p p { [ 1 + 5 / 100 ] 2 - 1 } = 246 p ( 5 / 100 ) ( 2 + 5 / 100 ) = 246 [ a 2 - b 2 = ( a - b ) ( a + b ) ] p = 246 / ( 0.05 ) ( 2.05 ) = 2400 . amount = rs . 2646 answer : b"
add(divide(246, subtract(power(add(const_1, divide(5, const_100)), const_2), const_1)), 246)
