Find the missing number?
A.
85
B.
79
C.
87
D.
82
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
Logic: Next number ( Even Placed ) = Previous Number + Sum of the digits of previous number.
Next number ( Odd Placed ) = Previous Number + Sum of the digits of previous number - 12.
79 = 71 + 7 + 1 ( Even Placed )
67 = 79 + 7 + 9 -12 ( Odd Placed )
80 = 67 + 6 +7 ( Even Placed )
68 = 80 + 8 + 0 - 12( Odd Placed )
x = 68 + 6 + 8 = 82( Even Placed )
Thus, Missing number = 82.
