Question

The table shows the number of pupils in five primary classes. Each pupil donated \[Rs.10\] to the foundation for the elderly. How much did they donate altogether?

Class	\[4A\]	\[4B\]	\[4C\]	\[4D\]	\[4E\]
Number of pupils	\[38\]	\[40\]	\[39\]	\[37\]	\[38\]

Answer 1

Hint: The given table shows the number of pupils in each class. It is given that each pupil donated \[Rs.10\] to the foundation for the elderly. We are asked to calculate the total amount donated by all pupils.
We shall calculate the total number of pupils so that we are able to calculate the total amount paid by them.
After summing all the numbers of pupils, we multiply the total \[Rs.10\] to obtain the desired results.

Complete step by step answer:
From the above-given table, we can understand that the number of pupils in each class are \[38\] , \[40\] , \[39\] , \[37\] and \[38\] .
We shall calculate the total number of pupils so that we are able to calculate the total amount paid by them.
Hence, the total number of the pupils \[ = 38 + 40 + 39 + 37 + 38\]
On simplification by adding each term we get,
 The total number of the pupils \[ = 192\]
It is given that each pupil donated \[Rs.10\] to the foundation for the elderly.
We are asked to calculate the total amount donated by all pupils.
After summing all the numbers of pupils, we multiply the total \[Rs.10\] to obtain the desired results.
Therefore, the total amount denoted \[ = {\text{Rs}}{\text{.}}\,\,192 \times 10\]
After multiplying the terms with \[10\] , we get
Total amount donated \[ = {\text{Rs}}{\text{.}}\,\,1920\]
Thus, the amount donated by all pupils is \[{\text{Rs}}{\text{.}}\,\,1920\] .

Note: On this occasion, we add all those values of the number of pupils from the above table mentioned. And this is an ungrouped data type. To calculate the table values we actually need the observation in which the table value has the particular allocations on its own depending on the table. Also from the statistical data we identify all the characteristics and the resources like goods, expenses in objects, warehouse expense, and so on can also be tally over the concept of statistics.
