Question

Identify the method in which the population is divided into a number of groups and certain numbers of items are taken from each group at random.​

Answer 1

The present lockdown due to COVID 19 has resulted in temporary suspension of

businesses and services provision. The professionals like Doctors, Engineers, Teachers

and Lawyers etc. are no more in a position to continue the provision of their professional

services to earn their livelihood. Keeping the concept of opportunity cost in mind,

identify or assume at least three such professionals from your closest social circle and

work out the opportunity cost they have been bearing to stay at their home.
