Find the number in the place marked (?).
The number in the figures in Questions 1, 2 follow a pattern. Find the number in the place marked (?).

(a) 9 (b) 8 (c) 7 (d) 
(a) 16 (b) 8 (c) 10 (d) 2
 (b) 8
Explanation:
Sum of the square of 2 and 3 =4 + 9
= 13,
Sum of square of 7 and 3 = 49 + 9
= 58Sam as,
(5)^2 + (?)^2 = 89
25 + (?)^2 = 89
(?)^2 = 89 – 25
(?)^2 = 64
Square root on both side,
? = 8Then the value of ? is 8.
Hence, the correct answer is option (b) 8.
 (c) 10
Explanation:
2 x 4 = 8, 2 x 6 = 12, 3 x 12 = 36Same as,
? x 2 = 20
? = 20/2
? = 10Then, the value of ? is 10.
Hence, the correct answer is option (c) 10.
