Question

The mean and the median of seven distinct positive integers is 30. If the seven integers are such that their product is maximum, what is the product of the smallest and the largest integers?

Answer 1

Answer:

891

Step-by-step explanation:

It is mentioned that the mean and median is 30 for seven distinct positive integers and we know that median is the middle value exists in the data and we can asses the data values as we know that the data value must be consecutive.  So the  data values will be 27,28,29,30,31,32,33

Also mean is sum of data values divided by the number of data values so mean=30

sum of value/n=30

sum of values/7=30

sum of values=30*7=210

and sum of assessed data values is 27+28+29+30+31+32+33=210. Hence the data values are verified.

Hence the product of smallest and largest integer=27*32=891
