Answer:
12
Step-by-step explanation:
Data provided in the question:
Number of numerically limited visas approved = 4.5 million
= 4,500,000
Visas available each year = 366,000
Now,
Worth of visas approved in years
= [ Number of numerically limited visas approved ] ÷ [ Visas available each year ]
= 4,500,000 ÷ 366,000
= 12.23
hence,
worth of visas approved are over 12 years [ as 12.23 is over 12 ]
