Question

The ratio of illiterate to literate people in a locality is 1: 19. The population of that locality is 64000. How many among these are literate? And how many are illiterate?


Solution

Ratio of illiterate to literate people in a locality = 1:19

Ratio of literate people to the total number of people in the locality = 19:20

Total population of the locality = 64000

Number of literate people in the locality = × 64000

= 19 × 3200

= 60800

Number of illiterate people in the locality 

= Total population of the locality Number of literate people in the locality

= 64000 60800
