Question 1030280
Let their ages be {{{ a }}}, {{{ b }}}, and {{{ c }}}
-------------------
(1) {{{ a*b*c = 36 
(2) {{{ a + b + c = 13 }}}
----------------------
There are 3 unknowns, but only
2 equations, so guessing is the
only way I know how to do it
----------------------
I'll try
(2) {{{ 3 + 4 + 6 = 13 }}}
Numbers are too large because:
(1) {{{ 3*4*6 = 72 }}}
--------------------
I'll try
(2) {{{ 3 + 2 + 8 = 13 }}}
(1) {{{ 3*2*8 = 48 }}}
--------------------
I'll try
(2) {{{ 2 + 2 + 9 = 13 }}}
(1) {{{ 2*2*9 = 36 }}}
---------------------
Two of them are 2 yrs old
One of them is 9 yrs old
---------------------
I don't know if that's the only
solution
