Answer:

Step-by-step explanation:

$\bf\underline{Given \: :-}$

Number of people knows English = 800

Number of  people knows Punjabi = 50

Total number of people = 1200

$\bf\underline{To \: Find \: :-}$

a) Percentage of people knows English.

b) Percentage of people knows both Punjabi and English

$\bf\underline{Solution \: :-}$

Percentage People knows English = People who knows English/Total number of people × 100

$\sf=\frac{800}{12}$

$\bf= 66.67 \: \%$

Number of people knows both English and Punjabi = Total number of people - People who knows (English + Punjabi)

$\sf=1200 - (800 + 50)$

$\bf=350$

Percentage of people who knows both Punjabi and English  = People knows Punjabi/Total number of people × 100

$\sf=\frac{350}{1200} \times100$
