B) 42, 12
C) 63, 18
D) 83, 20
Correct Answer: D
Solution :
Except the number pair 83, 20, in all other pairs, the two times of the second number is equal to the number obtained by reversing the digits of the first number. \[64,23\Rightarrow 23\times 2=46\] \[42,12\Rightarrow 12\times 2=24\] \[63,18\Rightarrow 18\times 2=36\]You need to login to perform this action.
