If the number of females is 16.66% of the number of males. 90% females and 30% of males are educated. If the number of uneducated males is 12,300 more than that of uneducated females what is the total population? Correct Answer 2,10,00

Let the number of males 600x.

∴ The number of females will be 100x.

∴ Total population = 600x + 100x = 700x

The number of educated females = 100x × 90/100 = 90x

∴ The number of uneducated females = 100x – 90x = 10x

The number of educated males = 600x × 30/100 = 180x

∴ The number of uneducated males = 600x – 180x = 420x

According to the questions

⇒ 420x – 10x = 12,300

⇒ x = 30

∴ Total population = 30 × 700 = 21,000
