the l . c . m . of 2 numbers is 30 . 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 = 30 x = 5 the numbers are = 10 and 15 required sum = 10 + 15 = 25 answer is b"
add(multiply(divide(2, multiply(30, 2)), 2), multiply(divide(2, multiply(30, 2)), 30))
