Question : Directions: The total age of a mother and her daughter is 60 years. The difference between their ages is 30 years. Find out the age of the mother.
Option 1: 55 years
Option 2: 40 years
Option 3: 45 years
Option 4: 50 years
Correct Answer: 45 years
Solution :
Let the age of the mother be A years and the daughter be B years.
Then, A + B = 60 years
A – B = 30 years
Solving the above two equations,
⇒ 2A = 90
⇒ A = 90 ÷ 2 = 45
⇒ A = 45 years
So, the age of the mother is 45 years. Hence, the third option is correct.
