Problem: the ratio of 2 numbers is 2 : 3 and their h . c . f . is 10 . their l . c . m . is ?
Rationale: "let the numbers be 2 x and 3 x their h . c . f . = 10 so the numbers are 2 * 10 , 3 * 10 = 20,30 l . c . m . = 60 answer is b"
annotated_formula: sqrt(divide(10, add(power(3, 2), add(power(2, 2), power(2, 2)))))
