Population of City A = 200

Literates in City A = 150

Population of City B = 200/ (2/3) × 100 = 300

Literates in City B = 200

Population of City C = 150

Literates in City C = 50

Population of City D = 120

Literates in City D = 120 × 25/100 = 30

⇒ Total population of all the city = 770

⇒ Total Literate population of all the city = 430

∴ Literate Population = 430/770 × 100 = 55.84%
