Solution :-

Mean of 3 numbers = 25

The mean of 4 numbers = 48

According to the question,

Total of 3 numbers = 25 * 3 = 75

Total of 4 numbers = 48 * 4 = 192

Therefore,

Number of outcomes = 4 + 3 = 7

Total number of outcomes = 75 + 192 = 267

Mean = 267/7 = 38⅐

Therefore, the mean of all numbers is 38 ⅐.
