Options

A. 18
B. 21
C. 24
D. 15

Answer

B

Explanation

The pattern is as follows: Product of vertically opposite numbers + Position of the letter in alphabet series=Sum of two horizontally opposite numbers.
` therefore` Position of letter M in alphabet series = 13th
Position of letter R in alphabet series = 18th
Position of letter K in alphabet series = 11th
So,` (29 xx 35) + 13 (=M)=665` + 363 or 1028 = 1028
Similarly, `(18 xx 13) + 18 (=R)= 97 + 155 or, 252=252 `
Let the missing number be x.
` (8 xx 15) + 11 (=K)= 110 + x or, 120 + 11 = 110 + x or, x = 131 - 110 = 21`
Therefore, Missing number = 21
