Country A is said to dominate B or A > B if A has higher percentage in total coverage for both drinking water and sanitation facilities, and, B is said to be dominated by A, or B < A.

A country is said to be on the coverage frontier if no other country dominates it. Similarly, a country is not on the coverage frontier if it is dominated by at least one other country.

Using only the data presented under ‘sanitation facilities’ columns, it can be concluded that rural population in India, as a percentage of its total population is approximately

  1. 76
  2. 70
  3. 73
  4. Cannot be determined

Two equations :

Rural Population = R

Urban Population = U

Total Population = T

Therefore : U + R = T

From the data in sanitation table :
Urban Population with Sanitation + Rural Population with Sanitation = Total Population with Sanitation

Therefore : 0.7*U + 0.14*R = 0.29*T

0.7*(T – R) + 0.14*R = 0.29*T

0.7*T – 0.7*R + 0.14*R = 0.29*T

0.56*R = 0.41*T

R = 0.73 *T

Rural Population is 73 % of Total Population
