11. Average daily wages for 250 workers in a factory is Rs. 30 and that of 200 workers in another factory
is Rs. 35. The average daily wages of the workers of the two factories combined is:
a) Rs. 36.05
(b) Rs. 32.22
(c) Rs. 29.85
(d) Rs. 31.72​

Answer 1

answer:-(b) 32.22

explanation:-

Average is the sum of the data values divided by the total number of data values.

Given that, average daily wages of 250 workers in a factory A is Rs. 30

30= sum of 250 workers daily wages/250

sum of 250 workers daily wages= 7500

Average daily wages of 200 workers in a factory B is Rs. 35

35= sum of 200 workers daily wages/200

sum of 200 workers daily wages = 7000

Total average is

sum of 250workers daily wages + sum of 200 workers daily wages/250+200

7500+7000/450

=32.22

Therefore, the average daily wages of all workers of both the factories is 32.22
