Options

A. 2
B. 10
C. 6
D. 9

Answer

D

Explanation

The pattern is as follows:
Number in the circle = square root of sum of numbers in the triangle i.e. `sqrt((12+29+23) ) sqrt64 = 8 `
Similarly, `sqrt((17 + 3 + 5)) = sqrt25 = 5 `
Therefore, Required missing number ` = sqrt(9+49+23) = sqrt81 = 9`
