Guess the 5 digit number? hint: number is divisible by 2, average of all numbers is 5, last two digits are divisible by 7, and together the number formed by last 2 digits is less than 70 , the number is less than 50000, the middle digit is 7 and first 2 digits aqre divisible by 11, their is only 1 odd digit.

Answer 1

The five digit number is 44728

Step-by-step explanation:

The hints given are:

Number is divisible by 2 ⇒ 44728/2 = 22364 (perfectly divisible)

Average of all numbers is 5 ⇒ (4 + 4 + 7 + 2 + 8)/5 = 25/5

Last two digits are divisible by 7 ⇒ 28/7 = 4

Together the number formed by last 2 digits is less than 70 ⇒ 28 < 70

Number is less than 50000 ⇒ 44728 < 50000

Middle digit is 7 ⇒ 44728

First 2 digits are divisible by 11 ⇒ 44/11 = 4

Their is only 1 odd digit ⇒ '7' is the only odd number

Thus, the number is 44728.
