in school there are some bicycles and 4 wheeler wagons. one tuesday there are 190 wheels in the campus. how many bicycles are there?
multiply(divide(190, add(multiply(4, const_2), const_2)), const_2)
let no . of bicycles be x & no . of wagons be y so , 2 x + 4 y = 190 by solving , we get no . of bicycles = 39 ( wheels = > 2 * 39 = 78 ) no . of wagons = 28 ( wheels = > 4 * 28 = 112 ) answer : e
