Answer: mean = 339
Step-by-step explanation:
Take out median from mean 225, 275,325, 375, 425 and multiply each median with respective frequency 6,8,14,10,12 than you will get fm of each multiple 1350, 2200, 4550, 3750, 5100 now, at last add all frequency you will get 50 again now add all fm you will get total 16950
As we know,
mean = sum of fm/ sum of frequency
= 16950 / 50
= 339
