Question Analysis:
The average age of a husband and wife was 30 years, 4 years ago. We need to determine their current average age.
Given:
- The average age of the husband and wife was 30 years, 4 years ago.
Approach:
Let's assume the present age of the husband and wife to be H and W, respectively. We can use the concept of average to solve this problem.
Solution:
Step 1: Calculate the sum of ages 4 years ago.
- 4 years ago, the husband's age would be H - 4.
- 4 years ago, the wife's age would be W - 4.
The sum of their ages 4 years ago would be (H - 4) + (W - 4).
Step 2: Calculate the present sum of ages.
- The present age of the husband is H.
- The present age of the wife is W.
The present sum of their ages would be H + W.
Step 3: Use the concept of average.
- The average age 4 years ago was given as 30 years.
- According to the concept of average, the sum of ages divided by the number of people will give the average.
Therefore, we can set up the equation:
(H - 4) + (W - 4) / 2 = 30
Step 4: Solve the equation.
(H - 4) + (W - 4) = 60
H + W - 8 = 60
H + W = 68
Step 5: Calculate the present average age.
To find the present average age, we divide the present sum of ages (H + W) by the number of people (2).
Present average age = (H + W) / 2
Present average age = 68 / 2
Present average age = 34
Conclusion:
Therefore, the present average age of the husband and wife is 34 years. Option B is the correct answer.
