Alan's parents are both in their forties. the sum of their ages is eighty-four. the product of their ages is 1,763. how old is alan's oldest parent?

As both of them are at their forties which means they are above forty
then: we take an example of 41 and 43

1) the sum of the two ages is =84 then (41+43=84)
2)the product of the two ages is 1763 then (41x43)
41
x43

123
164

1763
.: his oldest parent is 43 yrs old
