Answer 1

Monthly Salary Mode = Rs 7727.27  

Step-by-step explanation:

Less than 5000       90

Less than 10,000    240

Less than 15,000    340

Less than 20,000    420

Less than 25,000    490

Less than 30,000    500

0 - 5000                90

5000 - 10000        150

10000 - 150000    100

15000 - 20000      80

20000 - 25000     70

25000 - 30000     10

Maximum frequency 150 lies 5000-10000

mode lies between 5000 - 10000

Mode = 5000  +  5000 *  ( 150 - 90)/(150 - 90 + 150 - 100)

= 5000 + 5000 * 60/110

= 5000 + 2727.27

=  7727.27

Monthly Salary Mode = Rs 7727.27
