the average of the first 5 multiples of 9 is :
solution : required average = ( total sum of multiple of 9 ) / 5 = ( 9 + 18 + 27 + 36 + 45 ) / 5 = 27 note that , average of 9 and 45 is also 27 . and average of 18 and 36 is also 27 . answer : option b
divide(add(add(add(add(9, multiply(9, const_2)), multiply(9, const_3)), multiply(9, const_4)), multiply(9, 5)), 5)
