Read Solution (Total 3)
-
- 18000*(110/100)*(120/100)=23760
- 11 years agoHelpfull: Yes(5) No(0)
- 10% of 18000 is 1800
After first year the population is 18000+1800
The total population becomes 19800
In second year the population becomes 20% of first year
So 20% of 19800 is 3960
19800+ 3960 gives 23760 - 7 years agoHelpfull: Yes(1) No(0)
- total populaton=18000
10% increase i.e 110
(110/100)*18000=19800
new population=19800 1st year
now during 2nd year it increases by 20% i.e 120
(120/100)*19800=23760 - 6 years agoHelpfull: Yes(0) No(0)
