Choose the set of numbers, similar to the set (31, 19, 41) out of the following:
Α. (27, 29, 47)
Β. (23, 34, 49)
C. (29, 16, 41)
D. (29, 17, 37)
Ε. (23, 37, 49)
Choose the correct answer from the options given below:

Correct option is D

Solution:

Set (31, 19, 41) can be decoded as:
First number + second number - 9 = (31+19) - 9 = 50 - = 41
Similarly for other sets:
A. (27, 29, 47 ) = (27 +29 ) - 9 = 56 -9 = 47
B. (23, 34, 49) = ( 23+34) - 9 = 57 - 9 = 48
C. (29, 16, 41) = (29+16) -9 = 45-9 = 36
D. (29, 17, 37) =(29+17) -9 = 46-9 = 37
E. (23, 37, 49) =(23+37) - 9 = 60-9 = 51

Only A and D follow the code
So option(d) is correct
