On mixing the colours yellow and cyan, the colour obtained is __________ .A. redB. blueC. greenD. black

Answer» Correct Answer - C
When the colours red and green are mixed , we get the colour yellow.
R + G = yellow (1)
Also, when blue and green are mixed we get the colour cyan.
Blue + Green = Cyan (2)
Adding eqn (1) and (2)
Yellow + cyan = (R+G+B) + G = W + G = G
Hence, by mixing yellow and cyan, we get the colour green.
