Answer: Option
Explanation:
Sum of the present ages of husband, wife and child = (27 x 3 + 3 x 3) years = 90 years.
Sum of the present ages of wife and child = (20 x 2 + 5 x 2) years = 50 years.
Husband's present age = (90 - 50) years = 40 years.

@ALL.
Members average-years ago=average age.
((h+w+c)/3)-3=27.........=90.
n0w average age of wife and child.
((w+c)/2)-5=20............=50,
So, 90-50=40 years.
Members average-years ago=average age.
((h+w+c)/3)-3=27.........=90.
n0w average age of wife and child.
((w+c)/2)-5=20............=50,
So, 90-50=40 years.

@PRIYA.
[(h-3)+(w-3)+(c-3)/3] = 27.
[(h+w+c-9)/3] = 27.
[(h+w+c)/3]+(9/3) = 27.
[(h+w+c)/3] = 27+3 ====>h+w+c=30*3 ====>h+w+c=90.
Similarly w+c = 50.
[(h-3)+(w-3)+(c-3)/3] = 27.
[(h+w+c-9)/3] = 27.
[(h+w+c)/3]+(9/3) = 27.
[(h+w+c)/3] = 27+3 ====>h+w+c=30*3 ====>h+w+c=90.
Similarly w+c = 50.

@SUNDER
IN 2nd expression
{y+5(10)}/6 is wrong i think .
it has to be y*10+5*10 divided by 5 i think because father has died so only 5 members will be ther ..

(H+W+C)/3 = 27+3(add 3 to get present data).
H+W+C = 27*3+3*3 = 90.
(W+C)/2 = 20+5(to get present data).
W+C = 20*2+5*2 = 50.
So (H+W+C)-(W+C) = 40 years.
H+W+C = 27*3+3*3 = 90.
(W+C)/2 = 20+5(to get present data).
W+C = 20*2+5*2 = 50.
So (H+W+C)-(W+C) = 40 years.

Average of present ages of h,w,c=27+3=30
Average of present ages of w,c =20+5=25
so age of husband = 90-50=40
Average of present ages of w,c =20+5=25
so age of husband = 90-50=40

(H + W + C) - 3 * 3
-------------------------- = 27
3
(W + C) - 2 * 5
------------------------- = 20
2
Solving this We get the solution.
-------------------------- = 27
3
(W + C) - 2 * 5
------------------------- = 20

1. Before 3 years husband+wife+child = 27.
Now = 30*3 = 90.
2. Before 5 years wife+child = 20.
Now = 25*2 = 50.
Husband age = 90-50 = 40.
Now = 30*3 = 90.
2. Before 5 years wife+child = 20.
Now = 25*2 = 50.
Husband age = 90-50 = 40.

20+5 =25 today's average of w+child.
H+w+child is 27 +3 = 30 todays all average.
Difference is 5, So 5*2+ new avg30 = 40.
H+w+child is 27 +3 = 30 todays all average.
Difference is 5, So 5*2+ new avg30 = 40.
