14 that of his cousin's. How old is Albert now?

Albert |
Albert's cousin |
Difference |
Before |
1x2 = 2 u |
4x2 = 8 u |
3x2 = 6 u |
Change |
+ 28 |
+ 28 |
|
After |
3x3 = 9 u |
5x3 = 15 u |
2x3 = 6 u |
The difference in the age between Albert and Albert's cousin remains unchanged. Make the difference in age the same. LCM of 3 and 2 is 6.
Increase in the age of Albert
= 9 u - 2 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Albert's age now
= 9 u
= 9 x 4
= 36
Answer(s): 36
