Answer 2

Answer:

Option D

Step-by-step explanation:

average salary = (sum of the salaries)/(no.of workers)

given average salary= Rs1900

1900= (sum of salaries)/20

sum of salaries = 1900×20= Rs 38000

now manager salary is added

new average = 2000

2000= (38000+salary of manager)/21

2000×21= 38000+ salary of manager

salary of manager = 42000-38000

salary of manager= Rs 4000

option D
