There are two baskets containing the same number of balls. Each ball
is either red or blue. The percentage of red balls in the first
basket rounded off to the nearest tenth is 34.2%. The number of red
balls in the second basket is 11. Which basket has more red balls?

The first basket has more RED balls, it has 13 at least.

With natural numbers, the minimum values which can arrive at this percentage (34.2) is : 13 RED, 25 BLUE balls.

And hence the second basket will be 11 red, 27 blue balls.
