Show Answer

Correct Answer: (1)

Solution: (1)

New population in the year 2013 :

Town $A \Rightarrow 80000 \times \frac{60}{100} \times\frac{120}{100}+80000 \times \frac{40}{100} \times \frac{115}{100}$ $=57600+36800=94400$

Town $B \Rightarrow 75000 \times \frac{2}{3} \times \frac{120}{100}+75000 \times \frac{1}{3} \times \frac{115}{100}$ $=60000+28750=88750$

Required answer $=94400+88750=183150$
