Question We are the group of 5-digit numbers between 35,000 and 75,000 such that all of our digits are odd. Who is the largest number in our group? Who is the smallest number in our group? Who among us is the closest to 50,000?
5-digit numbers between 35,000 and 75,000 such that all of our digits are odd are as follows:
35,111, 35,113; 35,115; 35,117; 35,119; …; 39,999; 51,111; 51,113; …; 73,999.
So, the largest number of the group = 73,999
and, the smallest number of the group = 35,111
∴ The number closest to 50,000 = 51,111
