in how many years rs 100 will produce the same interest at 5 % as rs . 200 produce in 2 years at 10 %
"explanation : clue : firstly we need to calculate the si with prinical 200 , time 2 years and rate 10 % , it will be rs . 40 then we can get the time as time = ( 100 * 40 ) / ( 100 * 5 ) = 8 option a"
divide(multiply(divide(multiply(200, 10), const_100), 2), multiply(divide(5, const_100), 100))
