in how many years rs 200 will produce the same interest at 10 % as rs . 400 produce in 5 years at 12 %
"explanation : clue : firstly we need to calculate the si with prinical 400 , time 5 years and rate 12 % , it will be rs . 240 then we can get the time as time = ( 100 * 240 ) / ( 200 * 10 ) = 12 option c"
divide(multiply(divide(multiply(400, 12), const_100), 5), multiply(divide(10, const_100), 200))
