The combined areas of 2 circles with the same radius would be half the distance of a circle with double the radius. The reason is because you are doubling only the total area when you have 2 different circles. When you double the radius of the circle when finding the are ma you are actually doubling 2 dimensions, so you double it and then double it again making it 4 times as big.
We know that the mixture has 14 mm of ink. Of these, 35% are blue pigment, hence the mixture contains 4.9 mm of blue ink. Ink A contains 10%*4mm=0.4mm of blue ink. The difference, 4.5 mm of blue ink must have come from ink B. Thus ink B contains 4.5 mm of blue ink and is in total 10mm. After that, we can calculate the percentage; we divide 4.5/10=0.45 and this is the ratio of blue ink to total ink (in Ink B). If we transform it to percentages it is 45%
The answer is c hope this helps god bless and have a nice day sirr
