Dad what's the time

When I asked my dad how many minutes to six o' clock?
My dad a math teacher said this -
Fifty minutes ago it was four times as many minutes past three o' clock, how many minutes is it to six then?
Answer

Tall taller tallest

Next door to me live four brothers of different heights. Their average height is 74 inches, and the difference in heights amongst the first three men is two inches. The difference between he third and fourth man is six inches.

Can you guess how tall is each brother?
