Question

The mean of 5 number is 35.The mean of next four numbers is 50.Find mean of all the numbers

Answer 1

As per the data given in the question,

We have to determine the mean of the total 9 numbers.

As per question,

It is given that,

The mean of 5 number is 35.

The mean of next four numbers is 50.

As The mean of 5 number is 35.

So, sum of first five numbers will be $=35 \times 5 = 175$

As, The mean of next four numbers is 50

So, sum of next four number will be $=50 \times 4 = 200$

So, total sum of all numbers will be $175 +200 = 375$

Total numbers will be $5+4 = 9$

Hence, mean of 9 numbers will be $=\frac{375}{9} = 41.666 \approx 41.67$

Hence, means of all numbers will be 41.67.

Answer 2

From the data given in the question,

We have to find out the mean of the total $9$ numbers.

As per the givenquestion,

It is given that,

The mean of $5$number is $35.$

The mean of next four numbers is $50.$

As The mean of $5.$ number is $35.$

So, sum of first five numbers will be $=35 \times 5=175$

As, The mean of next four numbers is $50.$

So, sum of next four number will be =$50 \times 4=200$

So, total sum of all numbers will be $175+200=375$

Total numbers will be $5+4=9$

Hence, mean of 9 numbers will be   $=\frac{375}{9}=41.666 \approx 41.67$

So, means of all numbers will be $41.67.$
