40-60 : 80
60-80 : 60
80-100 : 20

Answer 1

Answer:

median of the prices = 32

Step-by-step explanation:

Price (Rupees) : No. of articles    Cumulatve Frequency

20 less than          140                    140

20-40                    100                    240

40-60                    80                     320

60-80                    60                     380

80-100                    20                    400

Median Lies in 20-40

Estimated Median = 20  + 20 * ((400/2) - 140)/100

= 20 + 20 * 60/100

= 20 + 12

= 32

median of the prices = 32
