Answer 2

Step-by-step explanation:

Given When the couple was married the average of their ages was 25 years. When their first child was born, the average age of family became 18 years. When their second child was born, the average age of the family became 15 years. Find the average age of the couple now

• So the average age of couple is 25 years
•         So their sum would be 25 x 2 = 50
• Now a child is born and hence total family is 3  
•          So average age is 18 years = 18 x 3 = 54 years
• Now the age of couple would have increased by 2 years each since age of child was 0
• So we get 50 + 2 + 2 = 54 years
• Now the second child was born so total will be 4 and so average age is 15 = 15 x 4 = 60 years
• Now the age of couple and first child would have increased by 2 years each since age of second child was 0.
• So we get 54 + 2 + 2 + 2 = 60 years.
• Therefore total age of the couple after 4 years will be 50 + 4 + 4 = 58 years
• So the average of the couple is 29 years.
