Answer:
There are eight sets
Step-by-step explanation:
The number of set of consecutive positive number whose sum is less then 30 are following
{1+2+3} {2+3+4} {3+4+5} {4+5+6} {5+6+7}{6+7+8 } {7+8+9} {8+9+10}
Because
1+2+3 = 6 < 30
2+3+4 = 9 < 30
3+4+5 = 12 < 30
4+5+6 = 15 < 30
5+6+7 = 18 < 30
6+7+8 = 21 < 30
7+8+9 = 24 < 30
8+9+10 = 27 < 30
9+10+11 = 30
Hence there are eight sets of numbers which satisfy the condition.
