Martina is currently 12 years older than her cousin Joey. In 2 years she will be 3 times as old as Joey.

It will be 14 because
\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
