Out of 6 plastic balls , three are black , two are white and one is of unknown colour. Out of seven leather balls , one is white , two are black and four are of unknown colour.
And there is also a green ball. So when we add all these colours , we see that all the white colour Balls have been engaged/adjusted and also the five black ones .
So there are still two back balls whose type of material is unknown. Also colour of one plastic ball and four leather balls is unknown.
So totally we have six plastic balls , seven leather balls , one green ball and the two black balls whose material make is unknown. So it totals 16.
