Answer:
4 times
Step-by-step explanation:
Given that the sum of all the numbers => 3+4+5+6+7+8+9+10 = 52
And we are to divide it into two sets such that the sum of set B is three times the number of sum of set A => Sum B = 3 * Sum A
Hence Total sum = Sum B + Sum A
Total sum ÷ 4 = 52 ÷ 4 = 13.
Since Sum B = (3 * Sum A) => (3 * 13 ) = 39
Therefore Sum B = 39 and Sum A = 13
To divide them into two sets
Sum A = (10, 3) = 13: Sum B = ( 4, 5, 6, 7, 8, 9) = 39
Sum A = (9, 4) = 13: Sum B = (3, 5, 6, 7, 8, 10) = 39
Sum A = (8, 5) = 13: Sum B = (3, 4, 6, 7, 9, 10) = 39
Sum A = (7, 6) = 13: Sum B = (3, 4, 5, 8, 9, 10) = 39
Hence, the correct answer is 4 times
