since 50 people have been inoculated, and that's 1/5 of the village people (that has been inoculated), then set up an proportion.
The proportion would be 1/5 equals 50/x and cross multiply/simplify to figure out the value of x or the total amount of people in the village.
So the answer would be 250 people in the village in total.
