Question 1137573
Let {{{ a }}} = Paul's mother's age now
{{{ a - 27 }}} = Paul's age now
---------------------------------------------
{{{ a - 27 + 5 = (1/4)*( a + 5 ) }}}
{{{ a - 22 = (1/4)*( a + 5 ) }}}
{{{ 4*( a - 22 ) = a + 5 }}}
{{{ 4a - 88 = a + 5 }}}
{{{ 3a = 93 }}}
{{{ a = 31 }}}
Paul's mother is 31 now
--------------------------------
check:
{{{ 31 - 22 = (1/4)*( 31 + 5 ) }}}
{{{ 9 = (1/4)*36 }}}
{{{ 9 = 9 }}}
OK
