calculate the average of all the numbers between 15 and 55 which are divisible by 4 .
explanation : numbers divisible by 4 are 16,20 , 24,28 , 32,36 , 40,44 , 48,52 , , , average = ( 16 + 20 + 24 + 28 + 32 + 36 + 40 + 44 + 48 + 52 ) / 10 = 340 / 10 = 34 answer : c
multiply(divide(add(add(floor(divide(15, 4)), const_1), floor(divide(55, 4))), const_2), 4)
