The mean weight of students of a particular class is $52\mathrm{kg}$. The mean weight of boys of this class is $56\mathrm{kg}$ and that of girls is $50\mathrm{kg}$. Find the ratio of number of boys to the number of girls in the class.

The marks of Nine students in ascending order for a test are given below with Median as $34$, the value of $k$ is:

$12, 16, k, 28, k+5, 32, 39, 47, 53$

The data below shows the number of wickets by each bowler and the number of bowlers who took them.

What is the median of the number of wickets?

Let $x$ be the median of data :$33, 42, 28, 49, 32, 37, 52, 57, 35, 41$.

If $32$ is replaced by $36$ and $41$ by $63$, then the median of the data, so obtained is $y$. What is the value of $\left(x+y\right)?$

What is the median of the given data?

$41,43,46,50,85,61,76,55,68,95$

What is the median of the given data?

$41, 43, 46, 50, 85, 61, 76, 55, 58, 95$.

What is difference between mean and median of the given data:

$4, 6, 3, 7, 10, 13, 16 \mathrm{and} 5?$

Find the range and mode of the data $17, 18, 28, 19, 16, 18, 17, 29, 18.$

$$\begin{gathered} 1. 12, 18 \\ 2. 13, 18 \\ 3. 12, 17 \\ 4. 11, 17 \end{gathered}$$

What is the mode of the given data?

$4, 3, 4, 3, 2, 2, 2, 5, 5, 3, 4, 6, 4, 3, 3$

What is the median of the given data?

$6, 2, 3, 5, 9, 4, 8, 7$

The mean and median of  $7, 5, 5, 2, 7, 6, 5, 3, 7, 6$is-

1. $5.3$ and $5$

2. $5$ and $5.5$

3. $5$ and $6$

4. $5.3$ and $5.5$
