The average age of a husband and his wife was 25 years when they were ...
Given:
- The average age of husband and wife 7 years ago was 25 years.
- The average age of husband, wife and his son now is 23 years.
To find:
- Age of son now.
Solution:
Let the present age of husband, wife and son be H, W and S respectively.
1. The average age of husband and wife 7 years ago was 25 years.
- 7 years ago, the husband's age would be H - 7 and the wife's age would be W - 7.
- So, (H - 7 + W - 7)/2 = 25
- H + W = 59
2. The average age of husband, wife and son now is 23 years.
- (H + W + S)/3 = 23
- H + W + S = 69
Using the above two equations, we can find the age of son:
- H + W = 59 (from equation 1)
- H + W + S = 69 (from equation 2)
- Subtracting equation 1 from equation 2, we get:
- S = 69 - 59 = 10
Therefore, the age of son now is 10 years.
Answer: Option (c) 5yr.
- The average age of husband and wife 7 years ago was 25 years.
- The average age of husband, wife and his son now is 23 years.
To find:
- Age of son now.
Solution:
Let the present age of husband, wife and son be H, W and S respectively.
1. The average age of husband and wife 7 years ago was 25 years.
- 7 years ago, the husband's age would be H - 7 and the wife's age would be W - 7.
- So, (H - 7 + W - 7)/2 = 25
- H + W = 59
2. The average age of husband, wife and son now is 23 years.
- (H + W + S)/3 = 23
- H + W + S = 69
Using the above two equations, we can find the age of son:
- H + W = 59 (from equation 1)
- H + W + S = 69 (from equation 2)
- Subtracting equation 1 from equation 2, we get:
- S = 69 - 59 = 10
Therefore, the age of son now is 10 years.
Answer: Option (c) 5yr.
