It must be b) 2.5

Out of 2 Gallons of mixture we need 3/4 gallons of White paint and 5/4 gallons of Black.

However since the quantity available is 1/2 gallons we need to take 1 Gallon White and 1.5 gallon Black paint.

For 2 Gallons

3 parts of white paint = (3/8)* 2 = 3/4

5 parts of black paint = (5/8)* 2 = 5/4

Since Both the paints are available only in 1 or 1/2 Gallons, we need to have

2 White containers of 1/2 gallon ( to make 3/4)

3 Black containers of 1/2 gallon ( to make 5/4) ( Or one Gallon container + One 1/2 Gallon)

So in total we need to buy 5* 0.5=2.5 Gallons of paint.
