Given :-

The mean of 3 numbers = 25

The mean of 4 numbers = 48

To find :-

The mean of all numbers.

Solution :-

Given that,

Mean of 3 numbers = 25

The mean of 4 numbers = 48

According to the question,

Total of 3 numbers = \sf 25 \times 3

\longrightarrow \sf 75

Total of 4 numbers = \sf 48 \times 4

\longrightarrow \sf 192

Therefore,

Number of outcomes = \sf 4+3=7

Total number of outcomes = \sf 75+192 =267

Finding the mean,

\underline{\boxed{\sf Mean=\dfrac{Total \ number \ of \ outcomes}{Number \ of \ outcomes} }}

Substituting their values,

Mean = \sf \dfrac{267}{7} =38\dfrac{1}{7}

Therefore, the mean of all numbers is 38 1/7
