Correct Answer: 45 years
Solution : Let the age of the mother be A and the age of the daughter be B.
The total age of a mother and her daughter is 60 years ⇒ A + B = 60 The difference between their ages is 30 years ⇒ A – B = 30
On adding both the equations, the equation becomes – ⇒ A + B + A – B = 60 + 30 ⇒ 2A = 90 ⇒ A = 90 ÷ 2 ⇒ A = 45
So, the age of the mother is 45 years. Hence, the second option is correct.
