2003: N: M = 1:6 Diff = 5
2012: N: M = 1:3 Diff = 2
Diff remains unchanged (Common Diff)
2003: N: M = 2:12 Diff = 10
2012: N: M = 5:15 Diff = 10
From 2003 to 2012 = 9 years
From N, 2u to 5u = 3u
3u = 9 years
1u = 3 year
Nurul in 2012 = 5u = 5x 3 = 15 years old
Nurul in 2016 = 15 + 4 = 19 years old.
Hope this helps.
