Martina is currently 12 years older than her cousin Joey. In 4 years she will be 3 times as old
Katarina [22]

\Huge{\underline{\underline{\sf{\red{AnSwEr:}}}}}

\boxed{\sf{Martina's \: Present \: age = 14 \: years}}

\boxed{\sf{Her \: cousin's \: Present \: age = 2\: years}}

\Huge{\underline{\underline{\sf{\green{ExpLaNaTion:}}}}}

= Let Martina's cousin's age be = n

= Let her age be = n+12

After four years,

Cousin's age = n+4

Her age = n+12+4=n+16

But according to the question her age = 3(n+4) = 3n+12

Thus,

3n+12=n+16

3n-n=16-12

2n=4

n=4/2

\boxed{ \sf {n = 2}}

Thus ,

Her cousin's present age = n = 2

Her cousin's present age = n = 2Her present age = n+12 = 2+12=14
