Explanation:

1). Given, 2 ≠ 7 ∆ 4
After interchanging the signs,
2 × 7 – 4 = 14 – 4 = 10

2). Given, 72 π27∆ 99
After interchanging the signs
72 + 27 – 99 = 99 – 99 = 0

3). Given 17 ≠ 12 \$ 3
After interchanging the signs,
17 x 12 / 3 = 17 x 4 = 68

4). 32 D4 B7 C2 A6
= 32 / 4 + 7 × 2 – 6
= 8 + 7 × 2 – 6
= 22 – 6 = 16

5). 40 B 8 T 6 M 3 K 4 = ?
40 / 8 – 6 + 3 × 4 = ?
5 – 6 + 12 = ?
17 – 6 = ?
? = 11

6). 1 P 4 5 R 2 Q 2 S 4
= 1 + 45 / 2 × 2 – 4
= 1 + 22.5 × 2 – 4
= 1 + 45 – 4 = 42

7). 6 % 12 C 3 @ 8 \$ 3 = ?
6 + 12 / 3 × 8 - 3 = ?
6 + 4 × 8 – 3 = ?
6 + 32 – 3 = ?
38 – 3 = ?
? = 35

8). -  ⇒  /
/ ×
+ -
×+
From option (a)
70 – 2 + 4 / 5 × 6 = 44
70 / 2 – 4 × 5 + 6 = 44
35 – 20 + 6 ≠ 44
From option (b)
70 – 2 + 4 / 5 × 6 = 21
70 / 2 – 4 × 5 + 6 = 21
35 – 20 + 6 = 21
21 = 21

9). -  ⇒  /
+ ×
/ -
×  ⇒ +
From option (a),
19 + 5 – 4 × 2 / 4 = 11
19 × 5 / 4 + 2 – 4 = 11
95 / 4 + 2 – 4 ≠ 11
From option (b)
19 × 5 – 4 / 2 + 4 = 16
19 + 5 / 4 – 2 × 4 = 16
19 + (5 / 4) – 8  ≠ 16
From option (c),
19 / 5 + 4 – 2 × 4 = 13
19 – 5 × 4 / 2 + 4 = 13
19 – 5 × 2 + 4 = 13
19 – 10 + 4 = 13
13 = 13

10). -  ⇒  /
+ ×
/ -
×+
From option (a),
30 – 6 + 5 × 4 / 2 = 27
30 / 6 × 5 + 4 – 2 = 27
5 × 5 + 4 – 2 = 27
25 + 4 – 2 = 27
27 = 27
