# A is two years older than B who is twice as old as C. If the total of the ages of A, B and C be 27, then how old is B ?

$\par&space;Let&space;C's&space;age&space;be&space;x&space;years.&space;then,$

$\par&space;B's&space;age&space;=&space;2x&space;years$

$\par&space;A's&space;age&space;=&space;(2x&space;+&space;2)&space;years$

$(2x&space;+&space;2)&space;+&space;2x&space;+&space;x&space;=&space;27$

$5x&space;=&space;25$

$x&space;=&space;5$

$\par&space;B's&space;age&space;=&space;2x&space;=&space;10&space;years.$
