Greatest number of 5 digits=99, 999
Smallest number of 5 digits=10, 000

The first 10 odd prime numbers are 3, 5, 7, 11, 13, 17, 19, 23, 29 and 31.

Sum of the odd prime numbers = (3+5+7+11+13+17+19+23+29+31)

= 158

Number of odd prime numbers = 10

prime numbers)

Average =

= 15.8

∴ The Average of first 10 prime numbers which are odd is 15.8

x = 65(x−8)

⇒5x=6x−48
