Question 2
Musa is three years older than Manya. Seven years ago, Musa was twice as old as Manya.
- How old are they now?
- When will the sum of them be 45?
Observation
The Chief Examiner reported that only a few of the Candidates’ attempted this question very well. It was expected if Musa’s age = x and Manya’s age = y,
then
x = y + 3……….. (1) and (x – 7) = 2(y – 7)…… (2)
Solving both equations will yield Musa’s age = 13 years and Manya’s age = 10 years. While for part (b), let n be the year when the sum of their ages will be 45, so that
(10 + n) + (13 + n) = 45 and solving will give n = 11 years.
