Options

A. 29
B. 22
C. 23
D. 32

Answer

B

Explanation

The pattern is as follows: The number in the centre of the triangle -Sum of the digits of all the three numbers at the vertices.
In the first triangle, 15 + 27 + 35 = (1 + 5) + (2 + 7) + (3+5)=23
In the second triangle, 13 + 35 + 20 = (1 + 3) + (3+5) + (2+0) = 14
Therefore, Missing Number in the third triangle = 42+36 + 70 = (4 + 2) + (3+6) + (7 + 0) = 22
