**Solution 2:**

**Solution 3(1):**

Product of the first and the fourth term = 2 × 49 = 98

Product of the second and the third term. 7× 14 = 98

Product of the first and the fourth term = Product of the second and the third term = 98

Hence, 2, 7, 14, 49 are in proportion.

**Solution 3(2)****:**

Product of the first and the fourth term = 3 × 35 = 105

Product of the second and the third term. 21× 5 = 105

Product of the first and the fourth term = Product of the second and the third term = 98

Hence, 3, 21, 5, 35 are in proportion.

**Solution 3(3):**

Product of the first and the fourth term = 2 × 11 = 22

Product of the second and the third term. 11× 4 = 44

Product of the first and the fourth term ≠ Product of second and third term

Hence, 3, 21, 5, 35 are not in proportion.

**Solution 1:**

Product of the first and the fourth term = 3 × 21 = 63

Product of the second and the third term. 7 × 9 = 63

Product of the first and the fourth term = Product of second and third term = 63

Hence, 3, 7, 9, 21 are in proportion.

**Solution 2:**

Product of the first and the fourth term = 7 × 13 = 91

Product of the second and the third term. 6 × 12= 72

Product of the first and the fourth term ≠ Product of the second and the third term

Hence, 7, 6, 12, 13 are not in proportion.

**Solution 3:**

Product of the first and the fourth term = 4 × 20 = 80

Product of the second and the third term = 8 × 10 = 80

Product of the first and the fourth term = Product of the second and the third term = 80

Hence, 4, 8, 10, 20 are in proportion.

**Solution 4:**

Product of the first and the fourth term = 10 × 24 = 240

Product of the second and the third term. 15 × 16 = 240

Product of the first and the fourth term = Product of the second and the third term = 240

Hence, 10, 15, 16, 24 are in proportion.

**Solution 5:**

Product of the first and the fourth term = 25 × 50 = 1250

Product of the second and the third term = 30 × 40 = 1200

Product of the first and the fourth term ≠ Product of the second and the third term

Hence, 25, 30, 40, 50 are not in proportion.

**Solution 6:**

Product of the first and the fourth term = 9 × 21 = 189

Product of the second and the third term. 11 × 20 = 220

Product of the first and the fourth term ≠ Product of the second and the third term

Hence, 9, 11, 20, 21are not in proportion.
