Answer 1

Answer:

275

Step-by-step explanation:

It is given that,

Total people  = 800

people speak french,  = 350

People speak German,  = 450

People speak only 3rd language = 25

Number of people speak only one language = 525

therefore we can write,

number of people speak both french, German  = 800  - ( 500) = 275
