4 u |
| Change |
+ 6 |
+ 6 |

| After |
2x4 =
8 u |
1x4 =
4 u |
1x4 =
4 u |
The difference in the age between Aunt Eva and Xylia remains unchanged. Make the difference in age the same. LCM of 1 and 4 is 4.
Increase in Aunt Eva's age
= 8 u - 5 u
= 3 u
3 u = 6
1 u = 6 ÷ 3 = 2
Aunt Eva's age 5 years from now
= 5 u + 5
= 10 + 5
= 15
Answer(s): 15
