Since the total number of people in the family is not given, the only way to do it is to list down the multiples of 6 and 10 and find a combination that makes 58.
Write down the multiples of 6 and 10:
Multiples of 6 = 6, 12, 18, 14, 30, 36, 42, 48, 54
Multiples of 10 = 10, 20, 30, 40, 50
Since multiples of 10s end with a "0" in the ones place, we are looking out for a "8" in the ones places in the multiples of 6.
Possible combination are
1) (3 x 6) + (4 x 10) = 56 [ 3 children and 4 adults ]
2) (8 x 6) + (1 x 10) = 56 [ 8 children and 1 adult ]
Answer: There can be 3 children and 4 adults or 8 children and 1 adult.
