two numbers are in the ratio 3 : 4 . if their l . c . m . is 48 . what is sum of the numbers ?
"explanation : let the numbers be 3 x and 4 x lcm of 3 x and 4 x = 12 x ( since lcm of 3 and 4 is 12 . hence lcm of 3 x and 4 x is 12 x ) given that lcm of 3 x and 4 x is 48 = > 12 x = 48 = > x = 48 / 12 = 4 sum of the numbers = 3 x + 4 x = 7 x = 7 x 4 = 28 answer : option a"
add(multiply(multiply(3, const_4.0), const_100), multiply(4, 48))
