Question 80: (February 28th, 2015) Answer



Answer: Answer: 26.
In the equations, 3/80 < 1/n, which means 80/3 > n.
Take an example, 1/3 < 1/2 implies 3 > 2.
So 26.666 > n.
Also 1/n < 4/101, which means n > 101/4 or 25.25.
As per the two conditions n is greater than 25.25 and less than 26.666.
Obviously n=26.
