Question

$a$ has to be a whole number such that $0\le a\le 10$. The solution for $a<4$ and $a\ge 6$ is:

• A. $5$
• B. $7$
• C. $3$
• D. no solution

Answer 1

The correct option is D no solution

Given set is $\{0,1,2,3,4,5,6,7,8,9,10\}$, the number $a<4$ are $\{0,1,2,3\}$ and the numbers $a\ge 6$ are $\{6,7,8,9,10\}$ . Since there are no common elements between the last two sets. Therefore, there is no solution if the inequality
