Answer 1

Step-by-step explanation:

from first place at the rate of 2 kg /Rs.=1kg

cost of 1 kg is = Rs .1 /2

in 2ndplace He bought @ 3 kg / rupees = Rs.1/3

in third place @ 4 kg per rupees = Rs. 1/4

in fourth place @ 6 kg per rupees = Rs. 1/6

total cost = 1/2 +1/3 + 1/4 +1/6 = 6+4+3+2/12

= 15/12

= 5/4

here sum of all observations = 5/4

total number of observation = 4

Average = sum of all observation

total number of observations

Average =5/4/4 = 5/16 =0.3125
