GIVEN:
The average age of husband, wife and their child 4 years ago = 26 years
wife and the child 5 years ago = 25 years
FORMULA USED:
Husband’s present age = Sum of the present ages of husband, wife and child - Sum of the present ages of wife and child
CALCULATION:
Sum of the present ages of husband, wife and child = (26 × 3 + 4 × 3) = 90
Sum of the present ages of wife and child = (2 × 25 + 5 × 2)
⇒ (50 + 10) = 60
Husband’s present age ⇒ (90 - 60) = 30 years

Given information:
The average age of husband, wife, and their child 4 years ago was 26 years.
The average age of wife and the child 5 years ago was 25 years.
Let's assume:
Present age of the husband = H
Present age of the wife = W
Present age of the child = C
Calculating the average:
Average age of husband, wife, and child 4 years ago = 26
So, (H-4 + W-4 + C-4)/3 = 26
H-4 + W-4 + C-4 = 26 * 3
H + W + C - 12 = 78
H + W + C = 90 ---(Equation 1)
Average age of wife and child 5 years ago = 25
So, (W-5 + C-5)/2 = 25
W-5 + C-5 = 25 * 2
W + C - 10 = 50
W + C = 60 ---(Equation 2)
Solving the equations:
From Equation 2, we can express W in terms of C:
W = 60 - C
Substituting this value in Equation 1:
H + W + C = 90
H + (60 - C) + C = 90
H + 60 = 90
H = 90 - 60
H = 30 years
Therefore, the present age of the husband is 30 years. Hence, the correct answer is option D.
The average age of husband, wife, and their child 4 years ago was 26 years.
The average age of wife and the child 5 years ago was 25 years.
Let's assume:
Present age of the husband = H
Present age of the wife = W
Present age of the child = C
Calculating the average:
Average age of husband, wife, and child 4 years ago = 26
So, (H-4 + W-4 + C-4)/3 = 26
H-4 + W-4 + C-4 = 26 * 3
H + W + C - 12 = 78
H + W + C = 90 ---(Equation 1)
Average age of wife and child 5 years ago = 25
So, (W-5 + C-5)/2 = 25
W-5 + C-5 = 25 * 2
W + C - 10 = 50
W + C = 60 ---(Equation 2)
Solving the equations:
From Equation 2, we can express W in terms of C:
W = 60 - C
Substituting this value in Equation 1:
H + W + C = 90
H + (60 - C) + C = 90
H + 60 = 90
H = 90 - 60
H = 30 years
Therefore, the present age of the husband is 30 years. Hence, the correct answer is option D.
