10400

Step-by-step explanation:

$per \: annum \: incresed \: 20\% \: in \: blood \: donor \\ 8000 \: blood \: donor \: in \: city \\ \frac{8000 \times 20}{100} = 1600 \\ find \: new \: donors \: in \: \frac{3}{2} yeas \: means \: 1.5 \: years \\ so \: = 1600(1year) +800(.5 \: or \: 6 \: months) \\ = 2400$

Total donors during 1.5 years

8000+2400=10400
