(d) First number = 8 and the sum of the digits of the second number is 2 + 8 = 10. Thus, the difference of the first number and the sum of the digits of second number is 10 - 8 = 2. Similarly, the sum of the digits of third number is 2 + 7 = 9. Hence, the sum of digits of fourth number should be 2 more than 9 i.e. 11 and 6 + 5 = 11 Hence, (d) 65 is the correct option.
