Problem: the l . c . m . of 2 numbers is 72 . the numbers are in the ratio 2 : 3 . find their sum ?
Rationale: "let the numbers be 2 x and 3 x l . c . m . = 6 x 6 x = 72 x = 12 the numbers are = 24 and 36 required sum = 24 + 36 = 60 answer is d"
annotated_formula: add(multiply(divide(2, multiply(72, 2)), 2), multiply(divide(2, multiply(72, 2)), 72))
