Answer Posted / kumar

ans is C.

let H be present age of husaband.W be present age of wife.

H+W=91.

now let diff between their ages be x.that is H-W=x.

now when husband is W yaers old, his wife must be W-x years
old.and it is given that H=2(W-x). so 2W-H=2x. and H-
W=x.eliminating x we get 4W=3H. but H+W=91, so solving thse
two H=52 W=39.
