The sum of the present ages of two persons A and B is 45. If the age of A is twice that of B, find the sum of their ages 5 years hence?	Choose the correct choice from the following:	A) 55	B) 60	C) 70	D) 80	E) 90
A + B = 45, A = 2B   2B + B = 45 =&gt; B = 15 then A = 30.   5 years, their ages will be 35 and 20.   Sum of their ages = 35 + 20=
