City A has 5,00,000 persons with a male-to-female ratio 3:2 and a literate-to-illiterate ratio 1:4. City B has 3,60,000 persons with ratios 4:6 and 4:1. City C has 2,80,000 persons with ratios 3:4 and 2:5. City D has 4,50,000 persons with ratios 5:4 and 3:2. City E has 5,00,000 persons with ratios 2:3 and 2:3.

A3:5
B2:5
C21:10 ✓ Correct
D8:3
Correct answer: (C) 21:10 — The ratio is 21 to 10, so the answer is 21 to 10.
Explanation
★The ratio is 21 to 10, so the answer is 21 to 10.
★City F has 3,00,000 persons with a literate-to-illiterate ratio 7:3.
★So its literates are 7 of 10 parts of 3,00,000, which is 2,10,000.
★City A has 5,00,000 persons with a literate-to-illiterate ratio 1:4.
★So its literates are 1 of 5 parts of 5,00,000, which is 1,00,000.
★The ratio of the two is 2,10,000 to 1,00,000.
★Dividing both by 10,000 gives 21 to 10.
