Problem: sum of two numbers is 63 . their difference is 1 / 8 of their sum . their l . c . m is
Rationale: "explanation : let the numbers be x and y according to the problem x + y = 63 x - y = 1 / 8 ( x + y ) x - y = 1 / 8 * 63 , x - y = 9 2 x = 72 , x = 36 and y = 27 l . c . m of 36 and 27 is 351 answer : option c"
annotated_formula: subtract(63, divide(subtract(63, divide(1, const_2)), const_2))
