calculate the average of all the numbers between 7 and 49 which are divisible by 6 .
"explanation : numbers divisible by 6 are 12 , 18,24 , 30,36 , 42,48 , average = ( 12 + 18 + 24 + 30 + 36 + 42 + 48 , ) / 7 = 210 / 7 = 30 answer : e"
multiply(divide(add(add(floor(divide(7, 6)), const_1), floor(divide(49, 6))), const_2), 6)
