Remaining population after percentage change = Initial population × (1 - Percentage change ).
To find the ratio of initial population to present population:
Ratio = Initial population ∕ Current population .
Calculation:
Remaining population after 15% left =P×(1−15∕100)
Remaining population =P×85∕100
Remaining population after 60\% of above left =(P×85∕100)×(1−60∕100)
Remaining population =(P×85∕100)×40∕100
Current population =(P×85×40)∕10000
‌3400=(P×85×40)∕10000
‌⇒P=(3400×10000)∕(85×40)
‌⇒P=34000000∕3400
‌⇒P=10000
Initial population =10000.
Ratio = Initial population ∕ Current population
Ratio =10000∕3400
⇒ Ratio =100:34
⇒ Ratio =50:17
