1.	The daily average wage of 50 workers is Rs 7.60. It was observed that daily wages of two workers were taken as Rs. 3.60 and Rs 6.80 instead of Rs. 8.40 and Rs. 5.30. Find the correct mean.
Answer» Answer:Average is the sum of the data values divided by the total number of data values. GIVEN that, average daily wages of 10 WORKERS in a FACTORY A is Rs. 30 ⟹30= 10 sum of 10 workers daily wages ⟹sum of 10 workers daily wages=300 Average daily wages of 20 workers in a factory B is Rs. 15 ⟹15= 20 sum of 20 workers daily wages ⟹sum of 20 workers daily wages=300 Total average is 10+20 sum of 10 workers daily wages + sum of 20 workers daily wages = 30 300+300 = 30 600 =20 Therefore, the average daily wages of all workers of both the factories is 20

Answer»

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

GIVEN that, average daily wages of 10 WORKERS in a FACTORY A is Rs. 30

⟹30=

sum of 10 workers daily wages

⟹sum of 10 workers daily wages=300

Average daily wages of 20 workers in a factory B is Rs. 15

⟹15=

sum of 20 workers daily wages

⟹sum of 20 workers daily wages=300

Total average is

10+20

sum of 10 workers daily wages + sum of 20 workers daily wages

300+300

600

=20

Therefore, the average daily wages of all workers of both the factories is 20
