Question

In U.K today the number of working women (reach) nearly 50% of working population.
Correct form of verb

Answer 1

the number of working woman reached

Answer 2

The right form of the verb will be “In UK, today the number of working women has reached nearly 50% of working population”.  

This is an example of present perfect tense.

The present perfect tense is used to narrate some event that has happened already, but the exact time of the event is not that vital.

It has a relationship with the present.
