Find the mean, median and mode of the given data.

Question

On the occasion of New year’s day a sweet stall prepared sweet packets. Number of sweet packets and cost of each packet is given as follows

Cost of packet (in ₹)	₹25	₹50	₹75	₹100	₹125	₹150
No of packets	20	36	32	29	22	11

Find the mean, median and mode of the given data.

Answer 1

N = Σf_i = 150 

Σf_i x_i = 12000

Mean = \(\overline x = \frac {\sum f_ix_i}{\sum f_i} = \frac {12000}{150} = 80\)

Median = average of (N/2 + 1 and N/2 terms) = average of 75 and 76 observation = 75

Mode = 50
