Answer:
35%
Step-by-step explanation:
The percentage of blue tint in paint mixture (a mixture of 200ml of green tint, 350ml of blue tint and 450ml of red tint) is the ratio of the quantity of blue tint to the total quantity of tint.
The total quantity of tint
= 200ml + 350ml + 450ml
= 1000ml
The percentage of blue tint in the paint mixture
= 350ml/1000ml * 100%
= 35%
