(i) Range of numbers = Highest number – Lowest number
= 62 – 42 = 20
(ii) 9 numbers are greater than 50
(iii) 6 numbers are between 40 and 50

The required frequency table will be as shown below:

Total		20

(i) There are 14 numbers are less than 19.
(ii) There are 2 numbers more than 20.
(iii) 9 is occurring most frequently i.e. 5 times.

The required frequency table will be as shown below:

Weekly wages in (₹)	Tally-marks	Frequency
750	|||	3
800	||||	4
850	|||	3
900	|||	3
950	||	2
Total no.of workers		15

(i) Workers getting less than ₹850 per week
No. of workers getting ₹750 = 3 workers
No. of workers getting ₹800 = 4 works
∴ Workers getting less than ₹ 850 = 4 + 3 = 7 workers
(ii) Workers are getting more than ₹800 per week
No. of workers getting ₹850 = 3
No. of workers getting ₹900 = 3
No. of workers getting ₹950 = 2
∴ Workers getting more than ₹800 = 3 + 3 + 2 = 8 workers
