Step-by-step explanation:

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 325x3

\longrightarrow \sf 75-75

Total of 4 numbers = \sf 48 \times 448x4

\longrightarrow \sf 192—192

Therefore,

Number of outcomes = \sf 4+3=74+3=7

Total number of outcomes = \sf 75+192

=26775+192=267

Finding the mean,

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

Mean=

Number of outcomes

Total number of outcomes

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