Correct Answer - Option 1 : 50
Given:
Company A = 53, company B = 45, company C = 23, company D = 43, company E = 86
Formula:
Average = sum of data/number of data

Total sum of bike in 2014 = 53 + 45 + 23 + 43 + 86 = 250
⇒ Required average = 250/5 = 50
∴ Average sale of bikes of all the companies in year 2014 is 50
