Fill the squares and win #1

It was carnival time. Borbo loved playing the carnival games. He stopped at Harbo and Bela’s booth to play two games. He carefully read the rules for game one.

Put 1, 3, 4, 5, or 6 (can’t use a number twice) in each empty square so that the column and row sums are as shown in the circles. The sum of 4 is a column sum and a row sum and the sum of 6 is also a column sum and a row sum. The sum of 11 is a row sum for the bottom row and a column sum for the rightmost column. Solve the problem in ONE MINUTE and win a prize.

Borbo started the minute timer and began to think and to add.
