Illustration 4 :
In a group of 1000 people, there are 750 who can speak Hindi and 400 who can speak Bengali. How many can speak Hindi only ?How many can spak Bengali ? How many can spak both Hindi and Bengali ?​

Answer 1

Step-by-step explanation:

no of people=1000

hindi=750 (1)

bengali=400 (2)

(1) +(2) =1150

now 150 are more

let no of people who speak both language be x

only hindi =750-x

only bengali =400-x

hence, 1150-2x+x=1000

x=150

hence hindi speaking =750-150=600

only bengali speaking =400-150=250
