6 u |
1 u |
5 u |
| Change |
+ 8 |
+ 8 |

| After |
2x5 =
10 u |
1x5 =
5 u |
1x5 =
5 u |
The difference in the age between Aunt Winnie and Julie remains unchanged. Make the difference in age the same. LCM of 1 and 5 is 5.
Increase in Aunt Winnie's age
= 10 u - 6 u
= 4 u
4 u = 8
1 u = 8 ÷ 4 = 2
Aunt Winnie's age 3 years from now
= 6 u + 3
= 12 + 3
= 15
Answer(s): 15
