From the following data, calculate the percentage of workers who earn more than $₹840$ per week.

Weekly wages (in ₹)	$500-600$	$600-700$	$700-800$	$800-900$	$900-1000$	$1000-1100$
No. of workers	$12$	$17$	$22$	$29$	$12$	$6$

 

Consider the following distribution :

Determine the pass marks if $85\%$ of the students pass the exam.

Consider the following distribution :

The marks which $45\%$ of the students exceed. Round off your answer to nearest integer.

Given below is the distribution of daily earning of $60$ workers in a factor :

If $55\%$ of the workers fulfill their requirements, find the minimum daily earning to meet the requirements of a worker.

Determine the value of the mode for the following sets of data:

$10,11,10,12,11,10,11,11,11,12,13,11,12$

Determine the value of the mode for the following sets of data:

In a class test, the marks (out of $10$) of $30$ students were:

$5,3,6,5,5,4,1,3,8,4,3,6,5,4,8,2,5,4,4,4,3,7,2,4,5,4,8,9,10,7$

Draw a tally chart and a frequency table. Hence, find
