what is the compound interest on rs . 7000 at 8.5 % p . a . compounded half - yearly for 5 years .
"compound interest : a = p ( 1 + r / n ) nt a = 10 , 613.50 c . i . > > 10 , 613.50 - 7000 > > rs . 3613.5 answer : b"
divide(multiply(multiply(multiply(const_3, const_100), const_100), multiply(5, divide(8.5, multiply(8.5, const_3)))), const_100)
