Balance Beams 2Math brain teasers require computations to solve.
Two beams (rows of numbers) are given below. The first beam has a sum of 17; the second beam has a sum of 22. Your challenge is to balance the beams, so that the two rows have the same sum. You are only allowed to move two numbers; all of the numbers must be used in the answer.
1 2 5 9
3 4 7 8
HintThe sum of all the numbers is odd.
One of the numbers must be moved in a tricky way to make a larger number.
AnswerMove the 1 to the bottom row, placing it immediately to the left of the 3, making a 13.
Move the 8 to the top row. Both beams now have a sum of 24.
8 2 5 9
13 4 7
