He have only 86 cows and dont have birds.
let suppose he have x number of cows and y number of birds. then
2x+ 2y=172 (because each have two eyes)
4x+ 2y= 344 (because cows have 4 legs and birds have 2 legs)
so x=86 and y= 0.

There are 86 cows only. There are 86 pairs of eyes, so there are 86 animals/birds. To make it 344 legs there should be 86 cows.

Jim keeps all his ties in a drawer.

He has 7 yellow, 10 blue, 9 red, 20 green and 3 purple colored ties.

He does not sort and keep them.

There is a power outage and Jim needs 2 ties of the same color.

Since he cannot see which color he is picking up from the drawer, how many ties does Jim have to take to be sure that he has at least 2 ties of the same color?
