Find the number in the place marked (?) in Questions 1, 2 and 3
The numbers in the following figures follow a pattern. Using this information, find the number in the place marked (?) in Questions 1, 2 and 3.

(a) 26 (b) 28 (c) 30 (d) 32 
(a) 3 (b) 4 (c) 5 (d) 6 
(a) 2 (b) 3/2 (c) 1/2 (d) 1
Explanation:
8 x 1 + 5 x 3 = 8 + 15
= 23,
8 x 3 + 3 x 1 = 24 + 3
= 27,
4 x 3 + 2 x 6 = 12 + 12
= 24,
 (a) 26
Explanation:
2 x 4 + 3 x 6 = 8 + 18 ,Hence, the correct answer is option (a) 26.
 (b) 4
Explanation:
4 x 1 + 5 x ? = 24
4 + 5 x ? = 24
5 x ? = 24 – 4
? = 20/5
? = 4Hence, the correct answer is option (b) 4.
 (c) 1/2
Explanation:
12 x 1/2 + ? x 12 = 12
6 + ? x 12 = 12
? x 12 = 12 – 6
? x 12 = 6
? = 6/12
? = 1/2Hence, the correct answer is option (c) 1/2.
