Solution

The correct option is A 4 L
Ratio of blue and yellow paints = 2 : 5
Amount of blue paint = 2x
Amount of yellow paint = 5x
6 litres more of yellow than blue is taken.
According to question, we get that $5 x - 2 x = 6$
$3 x = 6$
$x = \frac{6}{3}$
$x = 2$
Amount of blue paint $= 2 \times 2 = 4$ litres
