Solution
The correct option is A 16
Here, in each of the 4-digit number, the digit at ten's place is subtracted from the sum of digits at ones, hundreds and thousands place to get the corresponding resultant number.
2 + 8 + 6 = 16, 16 - 3 = 13;
9 + 4 + 3 = 16, 16 - 2 = 14.
Similarly, 7 + 2 + 9 = 18, 18 - 2 = 16.
Hence, option (A) is the correct answer.
