**Transcription (in Hindi):**
"(क) 2 से 100 के बीच में कितने अभाज्य संख्याएँ हैं?
(ख) 1 से 100 के बीच कितनी अभाज्य संख्याएँ हैं?"

**Translation (in English):**
"(a) How many composite numbers are there between 2 and 100?
(b) How many prime numbers are there between 1 and 100?"

### Solutions:

1. **(a) Composite numbers between 2 and 100:**

Composite numbers are numbers that have more than two factors. They are not prime numbers.

- The prime numbers between 2 and 100 are:  
  2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.  
  There are 25 prime numbers between 1 and 100.
  
- Total numbers between 2 and 100 = 99 numbers (from 2 to 100).
- Number of composite numbers = Total numbers - Prime numbers  
  = 99 - 25  
  = 74.

**Answer: There are 74 composite numbers between 2 and 100.**

2. **(b) Prime numbers between 1 and 100:**

As listed above, the prime numbers between 1 and 100 are the same 25 primes mentioned.

**Answer: There are 25 prime numbers between 1 and 100.**
