If the number is x, then 3x-8 is=or greater than 2x.

Agnus has x bones and Ignatz has x+5.

Then x+x+5=27 or 2x=27-5=22

Or x=11. Ignatz has 11+5=16.

Kathy mis x and John is x+10

Then x+x+10 is greater than 60

Or 2x+10is greater than 60

Or 2x 10 is greater than 50

Or x is greater than 25.

PS: There is slight typo.

Please readt first line as 'Kath is' and third line as 2x+10.
