Answer:
A greater percentage of blue T-shirts were sold.
see the explanation
Explanation:
we know that
To find out the percentage sold, divide the number of shirts sold by the total number of shirts and multiply by 100
so
White t-shirts
total shirts 200
shirts sold 120

Blue t-shirts
total shirts 300
shirts sold 240

therefore
A greater percentage of blue T-shirts were sold.
