If in Haripur, males infected by COVID-19 was 8436 and in Sitapur, females infected by COVID-19 is 30% less than the females infected by COVID-19 in Haripur, then find out the total number of people infected by COVID-19 in Sitapur.
Answer & explanation
Correct answer: option 2
Ratio of male to female infected by COVID-19 in Haripur = 6 : 5
6R = 8436
1R = \(\frac{8436}{6}\) = 1406
Females infected in Haripur = 1406 × 5 = 7030
Females infected in SItapur = 70% of females infected in Haripur
= \(\frac{7}{10}\) × 7030
= 4921
Now , Ratio of male to female infected in Sitapur = 2 : 1
As , 1R = 4921
So , Total infected population of Sitapur = 3 × 4921 = 14763
