To: CEO
Park lane Hospital
Central London,
09 - 06 -2021.
Respected Sir,
It is to bring into your knowledge about the spread of HIV/AIDS in the city. The people are unaware about the disease spread and those infected are carrying disease to others. There should be campaign run by the hospital to inform people about the spread of this contagious disease and preventions measures. 
There should also be special arrangement for the people infected by the disease to stay and live in a separate house so the spread can be stopped.  The hospital can allow people with symptoms for a free checkup so that more people can come and have their routine checkup. 
It is high time because if the spread will increase at the same rate then controlling the disease would become difficult. 
Regards,
John Andrews.

Answer: 15 million people were employed. 
Explanation:
Hi, to answer this question we have to multiply the adult population (25,000,000) by the labor-force participation percentage in decimal form (divided by 100).
Mathematically speaking:
25,000,000 x (60/100) = 25,000,000 x 0.6 = 15,000,000 people
15 million people were employed.
