Study the following table and answer the question:-

Number of cars sold by dealers P, Q, R, S and T during first six months of 2022.

What is the sum of average of cars sold by R in all months and average of cars sold by P, Q, R, S and T in March?

1305.66

Total cars sold by R = 640 + 635 + 640 + 540 + 625 + 740 = 3820

Average = 636.66

Cars sold by All 5 dealers in March = 628 + 635 + 640 + 722 + 720 = 3345

Average = 669

Sum = 669 + 636.66 = 1305.66
