To solve the problem, we need to find a number between 19 and 34 that is divisible by both 6 and 10.

First, let's determine the least common multiple (LCM) of 6 and 10.

  • The prime factorization of 6 is \(2 \times 3\).
  • The prime factorization of 10 is \(2 \times 5\).

The LCM is found by taking the highest power of each prime number that appears in the factorization:

  • The LCM of 6 and 10 is \(2^1 \times 3^1 \times 5^1 = 30\).

Now, we check if 30 is between 19 and 34:

  • 19 < 30 < 34

Thus, 30 is a valid solution.

Next, let's check the options provided:

  • 30 ✅
  • 20 ❌ (not divisible by both)
  • 60 ❌ (greater than 34)
  • 24 ❌ (not divisible by 10)

Therefore, the number that is greater than 19 and less than 34 that is divisible by both 6 and 10 is 30.
