The total age of a mother and her son is 60 years. The difference between their ages is 30 years. Find out the age of the mother
Show answer & explanation
Correct answer: B
Explanation
Let the mother's age be M years and the son's age be S years.
According to the question,
M + S = 60 ...(i)
M − S = 30 ...(ii)
Adding both equations,
2M = 60 + 30
2M = 90
M = 90 ÷ 2 = 45 years
Therefore, the mother's age is 45 years.
