the l . c . m . of 2 numbers is 54 . the numbers are in the ratio 2 : 3 . find their sum ?
"let the numbers be 2 x and 3 x l . c . m . = 6 x 6 x = 54 x = 9 the numbers are = 18 and 27 required sum = 18 + 27 = 45 answer is c"
add(multiply(divide(2, multiply(54, 2)), 2), multiply(divide(2, multiply(54, 2)), 54))
