find the difference between c . i and s . i on a sum of money rs . 2000 for 2 years . at 4 % p . a
p 9 r / 100 ) ^ 2 = 2000 ( 4 / 100 ) ^ 2 = rs . 3.20 answer : b
subtract(subtract(multiply(multiply(2000, add(const_1, divide(4, const_100))), add(const_1, divide(4, const_100))), 2000), multiply(2, multiply(2000, divide(4, const_100))))
